True story.

I couldn't make this up. My mother and I actually had this exchange tonight after we got home from my father's family's Christmas celebration.

Mom: "Your father is mad at me."
Me: "Well, he's a big A."
Mom: "Well, you know, it's always my fault."
Me: "Yeah, that's true, you are a pretty big B."
Mom: "Yeah. And you're a C."
(long pause)
Me: "Excuse me?"
Mom: "I'm still thinking about what a C could be... I thought of a couple - just forget I said that."
