For science (human biology), Mark's reading assignment was called "Getting Old" and was about aging. I said, "That's appropriate with my 41st birthday approaching."
He didn't respond.
I said, "Mark! That's when you're supposed to say, 'No, Mom, you're not old.'"
He said, "Well technically, Mom, you are. Forty is when you officially get old."
I said, "How do you know? Where did you hear that?"
He said, "A variety of sources."
Guess which one of my children doesn't get any birthday cake?
A variety of sources tells me he doesn't deserve any.
