I would be completely terrorized if someone made me take care of their children. I was a spectacular, abject failure at being a babysitter -- don't even get me started on the time one of my teachers came home to find me chasing the toddler around as she waved her diaper in the air while the three elder sisters had decided to take the antique footstool into the garage in order to use the Windex to clean the garbage can. Having to do that every day, all the time? GAAAAH!
There's a REASON I don't have kids of my own... you are a much braver soul than I am! XD
