<human>: This actually happened many, many years ago in day care. I'm posting now because I actually JUST remembered that this happened. So we were on a field trip to a large mall (I don't remember which one or why we did it), and we were about to go down an escalator. I was kinda scared of them back then, so I decided to wait around at the top of the escalator and look at the nearby stores. Well I stood there a little TOO long, and the principal of the day care (who was in the back of the group of kids) caught up to me and grabbed my arm tightly. Well I HATED being touched, and I still kind of do, so I naturally swung around and bit the person in the arm. She didn't cry, or really do anything. She just held on until I finally stopped biting her, tightened her grip, and pulled me all the way out of the mall, onto the bus that we took to get there, said something to the driver, and told me to sit down. She left the bus and I saw the doors shut. The bus took me back to the day care. When we got there, the driver told me to get out, and then the bus went right back out of the day care and to the mall. From what I remember, I just played in the gym until my mom got there to pick me up. I don't really remember anything after that, but I don't think my mom was informed by any of the day care staff that any of this ever happened, since she was happy to see me when she got there. Although looking back on it now, the whole thing started just 15 minutes after we arrived at the mall, and I know my mom paid 25$ for the trip... so in a way, the principal lady stole 25 dollars from my mom!
