While making a clay snowman with my son I didn’t like the proportions of the head to the body and decided it would be best to start over. Instead of just taking the clay and molding it into a ball and splitting it up again, I waved my hand above it like a big goof, and while making some sounds to my son smashed it into a flat disc and began to mold it back into two, more differently sized balls. He ran over to my wife and told her that the snowman had died.
To say I am hiding the concept of death from my son would be a lie, but I also would not think it is something he comprehends at his age. What shocked me was that he knew the word “died” in Japanese and was able to take the concept of me squashing the snowman and applying the word in that case.
