Poopy head

The worst thing about Lilli being 17 months? She can totally understand what I am saying, but it is completely reasonable for her, at 17 months, to pretend she doesn't know what I 'm saying, and she TOTALLY takes advantage of that. SO UNFAIR. She doesn't let ME get away with that crap. If I try to pretend I don't understand, she gets PISSED OFF. But if I try to to communicate something to her, and she doesn't want to understand, she just blissfully ignores me and gives me a hint of a wry smile, like "ha! you can't PROVE that I understand! I'm only 17 months old!" Then if I happen to get mad for once I feel sooo bad afterwards. I bet she doesn't feel bad when she gets mad at me. Poopy head.
