This morning as I was driving my son to pre-school, he suddenly said:

"Daddy is old."

"What do you mean?" I asked, wondering what a 4-year-old's concept of "old" could be.  "Daddy isn't that old," I continued.

"Yes he is," my son insisted.  "Daddy has wrinkles."

"Oh," I said.  After a pause, I asked, "Do you think I'm old?"

"No, you don't have any wrinkles, so you're young.  I'm young too," he said.

"What about Ah-ma (my mother)?  Is she old?" I asked.

"Well, she doesn't have any wrinkles either, so she's young too," my son said.

Hmm.
