One of the family tales goes like this: Aunt Bea got a new coat for Christmas one year, and she loved it. She loved it so much that she slept with it (for several nights, I think). And forever after, when Aunt Bea got something she really liked, something really special, she would tease and be teased about sleeping with it. So that became a sort of generalized joke in the family; when someone got something they'd really love, there'd be teasing about sleeping with it.
The thing is, Aunt Bea is one of those people that makes teasing a pleasure. Being teased about being just like Aunt Bea is like being teased about being beloved by everyone. That's just how Aunt Bea is.
I'm trying to figure out how to fit my new bike in bed.
