My earliest memory is from when I was a baby, maybe 2 or 3 years old. My family ran a daycare center in our house. It was the end of the day, when families were picking up there kids. I'm pretty sure I had bitten a kid that day (cause that was what I did back then). My mom was holding onto me so I wouldn't bite anyone else as she explained to the parents of the victim what happened. These circumstances weren't particularly memorable because I used to bite kids all the time, but I manage to still hold onto the memory. However, I tend not to bite people nowadays.
Although I had a different first memory, my second memory was very similar to this. I was in daycare (I think I was about 4 years old) and I used to bite people a lot, but on one particular day, I bit a kid on the face. He and I are still friends and we both still remember that day, but now we laugh about it.
