What is your first memory

[via Plinky]
This is actually a hard one. It seems that I can easily recall what happened a couple of hours ago, but as we go back in time things become a lot more hazy.
I can recall being a teenager, hanging out on a bit of land, down the road from my house with my friends, on our bikes, simply wasting an afternoon. When was that? I couldn't actually tell you! Sometime between 1992 and 1997, and I can only tell you that because one of my friends was a year older than me so went to University a year before I did.
Before that though, things happened, afterall I spent a year living in Malaysia in my aunt's house, with two dogs: a white, fluffy thing and a german shepherd. Now the german shephard was overly energetic, and affectionate, unfortunately also much larger than my little brother. So when the dog put its forelegs on his shoulders, he fell down, with the dog on top...Do I remember that? Or do I remember people telling me that was what happened? I honestly can't remember....
