bath tub conversations

... not sure where the conversation started, but it ended like this:

David: You have a sister now mom.
Me: Yes, Wonkyung is my sister. She married my brother, Uncle Pooh. One day you will have a brother David when Kate gets married and Kate will have a sister when you get married.
David: I'm not getting married.
Me: Why not?
David: I don't want to look different. (Patrick shaved for the wedding. It was traumatic for all of us.)
Kate: You don't have to wear a dress David.
David: Oh. Yeah.

Their logic makes perfect sense sometimes.
