My son’s ear muscles

I love parenting. It’s the toughest job in the world. But then you get gems like the conversation we had today.

My 9 year-old son: I wasn’t cold today. I think it’s my new ipod. The ear phones were in my ears so they were working harder.

Me (a bit incredulously): Do you mean to say your “ear muscles” were working harder? And that muscle work made your head warmer?

Son: Yeah.

My wife (matter-of-factly): Ah…do you suppose it could have been because of the hood you were wearing?
