I remember quite a bit, but I don't think there's anything that comes to mind before I was 4. I remember when I was told I was going to enroll in Kindergarden when I was 4. I remember watching Attack of the Clones on VHS in an apartment, and I also remember sitting in my mom's van while some guy was trying to rob it: a guy who came to the realization that I was in the car before bolting off. It was late at night, and we chased that guy around the town, but eventually lost him.
I also vividly remember running up some steps and smashing my left brow on the edge of one, enough to show bone in fact when I was 5 or 6. Didn't hurt at all, but I saw a pic taken like a week later and I had a humongous black scab on my eyebrow, but I was sitting there digging in the dirt with a dumb smile on my face.
One of the funniest things I don't remember is that one of my long-time school friends liked to constantly remind me that I used to call him "Dumpster Breath" before we became friends in Elementary School lol.
