a proposal, thankfully, rejected

This conversation transpired while I was at work last night:

Henry: (looking at our wedding picture on the wall) Look at that picture, Ceci. That's when Mommy and Daddy were brother and sister before they got married. Ceci, we are going to get married when we grow up, just like Mommy and Daddy.

Ceci: I'm not going to marry you. I'm gonna marry some other guy.

Patrick: Brothers and sisters don't get married. (At least not in this state...)

A timely exchange, seeing that today is our 10th wedding anniversary!
