Funny how even my youngest, who can't talk so well (even at 3), has acquired a skill in trash talkin. (I'm sure Jo's been teaching her things, cuz it's not me!) A couple weeks ago I was putting her to bed and had her brushing her teeth. I laid on her bed while she was going through the routine. When she saw me, she comes over and says promptly, "Daddy, move yur butttt." Shocked, Jo and I looked at each other with those smiles that only mean, "that's really funny, but whoa! And where did you learn that not-so-appropriate comment?" You know the look. If you have kids, you've certainly thrown a few at your spouse more than once when the kids say something you didn't expect.
Anyway, being a good dad, I asked Kristen if she could ask me to get up nicely. She immediately replied, "Otay. Daddy, move yur buttttt [p]leeze" ("p" omitted). At least she uses manners when trash talkin me.
