Past the age of four, it's all relatively clear, but before that I have just snippets.
For whatever reason, I have lots of memories of swimming. This is probably around age two. In particular, I remember this delicious chocolate milk that I got to drink every time I went swimming. Also, I remember being forced underwater by my parents once in an effort to get me to learn how to swim. Another thing I remember is intentionally letting my trunks slip off because they were uncomfortable (and then having them returned by some woman later).
Other than that, I remember, around three, being forced to sleep in the afternoon. And being told to watch TV while my parents were out. Routine things like this stuck in my head.
A fairly vivid memory is about when my sister broke her arm. At a party or such, we were competing with some other kids to see who could sit on the tallest stack of chairs. I chickened out quickly, but my sister, while trying to climb up, made the entire stack fall over on her and broke her arm in the process.
Other than that, I have an enormously painful memory of putting on some sort of pants with a zipper without wearing underwear. Not all that clear, but hurts just to think about it.
Looks like I remember quite a bit, though I guess I'm younger than most of you.
