My earliest memory that I can remember is when I was about 4. I was in preschool, and during playtime my friends and I alway played with these clip-like things that could clip to each other and to other things. Well, one day, we made a giant spider web out of them, and the my friend Tyler sat in the middle of it and brought everything that the clips were attached to came crashing down. This is what made it particulary memorable - my friends and I thought it was hilarious but we had clean up everything that we knocked down in the process.
I would say that my personality has changed since then - in preschool, I guess I didn't really care if I caused trouble, but during elementary school and still today I try to stay on the straight and narrow and don't really cause trouble at all. Yet, I still think that was me, as in I am continuous with that person, because I can recall memories in that transformation from a bit of a troublemaker to a goody two shoes.
