My son was six years old when he told me something on Halloween that I still think about every year.
He had gone trick-or-treating around our neighborhood that evening. I stayed nearby, letting him feel independent while still keeping an eye on him. About halfway down the street, I saw him stop beside an older woman standing outside her house. They talked for several minutes before my son waved goodbye and continued collecting candy.
I didn't think anything of it.
When we got home, he emptied his candy onto the kitchen table and started sorting everything into piles. I was putting away his costume when I remembered the woman he'd spoken to.
"Who were you talking to?"
He looked at me as though the answer was obvious.
"Grandma."
I smiled.
"Which grandma?"
"My grandma."
My smile disappeared.
My mother had died six years before my son was born. He had never met her. He had never heard her voice or held her hand. The only way he knew her was through the stories I told him and the photographs we kept around the house.
"Grandma isn't here," I said gently.
He shook his head.
"She came tonight."
Then he reached into his costume pocket and pulled out a small button.
"She told me you wouldn't believe me."
He placed it in my hand.
"She said to give you this."
I stared at the button.
It was old and slightly scratched, with one side worn smooth.
"Where did you get it?"
"From Grandma's coat."
That answer made me look toward the living room.
On our mantel was a framed photograph of my mother taken many years earlier. It was Halloween, and she was standing outside our old house holding a bowl of candy.
She was wearing a green wool coat.
My son had seen that photograph hundreds of times.
I had told him stories about her so often that he knew some of them by heart. One thing I always joked about was that my mother wore the same green coat almost every Halloween.
"Grandma's favorite costume was being Grandma," I used to tell him.
I looked back at my son.
"Was the woman wearing a green coat?"
He nodded.
"Just like the picture."
I sat down beside him.
"Tell me what happened."
According to my son, he had been walking toward the next house when he noticed the woman's coat. He recognized the color immediately and went over to her.
"You're dressed like my grandma," he had told her.
The woman laughed.
"Well, I suppose I'm your grandma tonight."
My son apparently thought that was perfectly reasonable.
They talked for a few minutes. Before he left, the woman noticed that one of the buttons on her sleeve was loose. She had been meaning to fix it, but instead she cut it off and gave it to him.
"Give this to your mom," she had apparently said.
She had no idea that the button might become important.
The next morning, I asked my son to show me where the woman lived.
We walked down the same street and found her outside.
My son immediately pointed at her.
"That's Grandma."
The woman smiled when she saw him.
"There's my little Halloween friend."
I introduced myself and explained what had happened. When I showed her the button, she recognized it immediately.
"Yes, that's from my coat."
I asked her where she had bought it.
She told me she'd found it at a secondhand store years earlier. She liked the color and bought it because it was warm. She had never known anything about its previous owner.
I hesitated before showing her the photograph of my mother.
She looked at it for a long moment.
Then she looked down at her own coat.
"That's an amazing coincidence," she said.
It wasn't the exact same coat. I knew that was impossible. My mother's photograph had been taken years before this woman had ever bought hers.
But the resemblance was unmistakable.
The same deep green color. Similar cut. Similar collar.
And then there were the buttons.
The one in my hand looked remarkably similar to the buttons on my mother's coat.
My son didn't care about any of those details.
As far as he was concerned, he had seen his grandmother.
He had recognized her coat.
She had called herself Grandma.
And then she had given him a button.
On the walk home, he held my hand and looked up at me.
"See? I told you she comes every Halloween."
I smiled.
"Yeah. You did."
I kept the button.
It's still in a small box with the few things I have left from my mother.
My son eventually stopped talking about that Halloween. As he got older, he forgot most of the details. He doesn't remember the woman's name, what her house looked like, or what they talked about.
But I remember everything.
I remember the photograph.
I remember the green coat.
And I remember the moment my six-year-old son placed that old button in my hand and told me that Grandma had sent it.
There is probably a simple explanation for what happened. A child saw a woman wearing a coat that reminded him of a photograph, and a kind stranger played along with his imagination.
That's probably the truth.
But every Halloween, when I take out that little button, I think about my mother and wonder whether some coincidences are simply too perfectly timed to feel ordinary.
I never told my son that the woman wasn't really his grandmother.
Maybe one day I will.
For now, I let him keep the memory exactly as he remembers it.
Because sometimes a six-year-old doesn't need an explanation.
Sometimes he just needs to know that Grandma came to see him.
