we took ava to the zoo last saturday. near the end, completely exhausted, we let her push the stroller out of the zoo. she was so excited she didn't notice that we'd exited until it was too late. then she sort of did this throw-your-self-on-the-concrete-and-cry thing which resulted in ryan carrying her to the car like this. after that, she continued to cry but not because she'd been tricked in to leaving the zoo.
