My first memory is one of my faves - it was when I went to go see my baby sister for the first time. She was just born so my grandparents took me to the hospital to see her, and I remember seeing toy's and thinking it was the best place ever. I didn't care about my sister, I just wanted to play.
I also remember playing with this boy when I was like 4, and all of a sudden like 10 jets came flying past, they were flying really low and we were running about screaming. I remembered this the other day and burst out laughing. I looked like an arse.
feel free to post your own, I'll add more later
