I am deciding whether we should teach Bobo some sign language so he can tell us deep thoughts like: "I hate you for not feeding me chocolate teddy grahams and in protest, I will hurl this binky at your head." Actually, he doesn't need sign language for that. That one is pretty clear.
Anyway, while trying to find a print out chart of some easy signs I could teach him, I found a video thing and discovered that the sign for "milk" is the motion one would make while milking a cow with one hand. I find this disturbing. Probably because I used to be the cow.
