I was a babysitter from age 13 to 18 or something like that. My information was available to people who needed someone to watch over their kids or pets; that's how I'd make money for my nerdy collectibles.
I can remember a pair of girls I'd babysit at least once a week for a while. I was specifically asked to NOT let them in the kitchen, else they'd devour all the sweets they could reach. To enforce that rule, I found one of those gates you can prop up between two walls to keep babies from going to a certain area. So I put that in the kitchen.
The girls were behaving very well. I got up, though, to answer the telephone and take a message for the mother who was out. While I had my back turned, the little monsters climbed the gate and got into a bag of homemade cookies. =___= The mother was displeased when she got home to find half of those cookies gone... The kids were grounded for being so disobedient, but I got in trouble, too. I explained that I was on the phone and showed her the message I took. That didn't seem to make her any less angry, though.
I hated having to deal with such strict, stuck up parents! It made lousy affects on my babysitting rep and sometimes, I'd get littler pay. *shakes head*
