Snowman Identity Over Time

An exchange with my five-year-old son:

“I just watched the Snowman movie. It’s kinda sad at the end.”

The Snowman“Why’s that?”

“Because the snowman melts. I hope the boy can build him up if it snows again.”

“But what if all the snow completely melts and there’s nothing left of him? If the boy builds up the snowman with new snow, would it be the same snowman or a different one?”

“I think it would be the same one.”

“Why do you think that?”

“Because the boy would use the same stuff to make him.”

“You mean the same hat, scarf, lumps of coal, and all that?”

“Yeah.”

“I think you could be right. Let’s hope it snows again.”
