The old man who came every Sunday to the pet store and only asked to hold the sickest dog. The first time Emma saw him, she thought he was lost. His coat was too big, his hands shook a little, and his eyes went straight past the fluffy puppies that made everyone else squeal.

“Do you have one that nobody wants?” he asked in a quiet, firm voice. “The one that’s been here the longest. Maybe… the sick one.”
Emma, twenty-two and new at the adoption center inside the pet store, blinked in confusion. Most people wanted the cutest, healthiest, youngest. She pointed hesitantly to a corner kennel where a small brown dog with cloudy eyes lay on a blanket.
“That’s Bruno,” she said. “He’s older. Heart problems. Medicine for life.”
The old man’s face softened in a strange way, like a memory had just sat down beside him.
“May I hold him?” he asked.
Company rules said customers could meet the dogs in the small playroom, so Emma led him there. She placed Bruno gently in his arms. The dog stiffened, then slowly relaxed, pressing his head against the man’s chest.
Emma watched as the old man whispered something into the dog’s ear. She could not hear the words, but she saw Bruno’s tail move, just a little. For forty minutes the man simply sat, cradling him, humming a tune that sounded like a lullaby.
When Emma came back to check on them, the man carefully handed Bruno over.
“Thank you,” he said. “I’ll be back next Sunday to see him. If… if he’s still here.”
“You could adopt him,” Emma suggested, half expecting his face to light up.
Instead, his eyes clouded over, matching Bruno’s.
“No,” he whispered. “Not yet.”
He left without buying anything. Just like that.
He came back the next Sunday. And the Sunday after that. Always alone, always in the same worn coat, always with the same question:
“Show me the one that hurts the most.”
Sometimes it was Bruno. Sometimes a limping spaniel, sometimes a terrified dog rescued from the street. He always chose the kennel none of the other families looked at twice. He always sat in the playroom, holding whichever dog needed warmth the most, humming that same soft melody.
The staff started calling him Mister Sunday.
At first, they joked about it in the break room. “Maybe he’s rich and secretly deciding who to leave his millions to,” one volunteer laughed. Another said, “Maybe he just likes being dramatic.”
Emma didn’t laugh. There was something in the way Mister Sunday’s fingers lingered on the dogs’ fur, in the way he closed his eyes when they finally relaxed. It looked like someone drinking water after crawling out of a desert.
One rainy afternoon, when the center was almost empty, Bruno’s cough was worse. Emma was alone on shift when Mister Sunday walked in, water dripping from his hat.
“Is Bruno still here?” he asked, breathing harder than usual.
Emma nodded. “He’s been waiting for you.”
She brought Bruno out. The dog’s chest rattled as he breathed, but as soon as he saw the old man, his tail thumped weakly.
Mister Sunday sank into the chair, hugging Bruno close, cheek against the dog’s head.
That day his humming broke halfway, turning into a shaky breath. Emma pretended to rearrange leashes just to stay nearby.
“Can I ask you something?” she finally said.
He looked up, eyes bright with moisture.
“Yes, child.”
“Why do you always choose the sickest one? Why not take one home?”
For a long time, he said nothing. The only sound was Bruno’s uneven breathing.
Then came the twist Emma never expected.
“I did take one home,” he said. “Her name was Lily.”
He stared at the far wall, but Emma could tell he was seeing something else entirely.
“She was small and broken, just like Bruno. Heart murmur, bad hips. The woman who ran the shelter begged me to pick a younger one. She said, ‘You’ll only have a few months with her.’” His lips trembled into a sad smile. “We had five years.”
He swallowed.
“My wife, Anna, she was sick too. Bedridden. Couldn’t move much. Lily would climb beside her, lie with her for hours, just breathing together. On the nights when the pain was worst, the dog would whine until I came, like she was calling for help.”
His fingers curled tighter into Bruno’s fur.
“When Anna died, Lily stopped eating. She spent days just lying on Anna’s pillow. One morning, she didn’t wake up.”
The room felt suddenly too small. Emma’s throat burned.

“I promised myself,” he continued, “that I wouldn’t take another dying creature home just to watch it leave. I’m not strong enough twice.”
He looked down at Bruno, whose eyes were half-closed, finally at peace.
“But what I can do,” he whispered, “is make sure that, for at least one hour a week, someone holds them like they’re the most important soul on earth. Someone hums to them. Someone tells them they are good, brave, loved. Even if they never find a family.”
His voice cracked on the last word.
Emma couldn’t speak. She stepped into the playroom, kneeling beside them.
“You know,” she said hoarsely, “they remember. Even if it’s just one hour a week. They remember being loved.”
He gave her a tired smile. “I hope so. I talk to them as if they understand.”
“What do you tell them?”
He hesitated, then answered in a whisper.
“I tell them I’m sorry I came too late for someone else.”
Those words lodged in Emma’s chest and never left.
Weeks passed. Mister Sunday kept coming, kept holding the ones that hurt the most. Sometimes he left with wet eyes. Sometimes the dog did.
Then, one sunny morning, the manager called everyone together.
“Good news,” she said. “Bruno found a home. An older couple with a quiet house. They’re picking him up this afternoon.”
The staff cheered. Emma’s first thought was, I need to tell Mister Sunday.
But Mister Sunday didn’t come that day.
He didn’t come the next Sunday either.
On the third Sunday, Emma stood by the door long after her shift, coat on, bag in hand, pretending to clean the counter again and again. The bell never rang.
The world felt slightly wrong, like a picture frame hung just a little crooked.
Finally, one of the volunteers said, “Hey, I think I saw a notice at the community board last week. An obituary. For a man named Richard Lewis. Looked a lot like your Mister Sunday.”
Emma’s hand froze mid-motion.
She found the small printed card the next day. A black-and-white photo. The same too-big coat, the same tired eyes. “Richard Lewis, beloved husband of Anna, devoted friend to many.” No children listed.
At the bottom, a single line: “In lieu of flowers, please support your local animal shelter.”
Emma read it three times before the words blurred.
That Sunday, she went to the back room where they kept the older dogs. A skinny grey mutt lay in the corner, back turned, not even lifting his head when she approached.
She opened the kennel, heart pounding.
“Hey there,” she whispered. “I’m Emma. I’m here to see the one that hurts the most.”
The sentence shook her as she said it. She picked up the dog, clumsy at first, then tighter, the way she’d seen Mister Sunday do it a hundred times.
She sat in the playroom, the dog against her chest, his heart beating nervously against her ribs.
Emma wasn’t good at humming, but she tried. It came out broken and off-key, but she didn’t stop.
“I don’t know the song,” she said softly, “but I know the feeling.”
Somewhere between one breath and the next, the dog’s body loosened. His head sank against her, his breathing slowed.
Emma’s tears fell into his fur.
“I don’t know if you remember every Sunday, Mister Sunday,” she whispered into the quiet room, “but I promise you this: they will.”
Outside, through the glass, the store was loud and bright, people rushing past, pointing at the fluffy puppies. Inside the little room, a girl who had been a stranger to pain was learning how to hold it gently.
From then on, every Sunday, there was always someone who came and asked the same question.
“Show me the one that hurts the most.”
They didn’t know his name, or his story, or the song he used to hum. But in the way they held the broken dogs, in the way they whispered, “You are loved, you are loved,” Mister Sunday came back, again and again, in every trembling hand that refused to let a hurting soul feel alone in its last hour.
