Seriously, I can't imagine not remembering anything from elementary school and middle school, hell, I remember my first grade vividly, the jokes we used to tell and the games my friends and I used to play on the school playground, the names of my teachers and even some memorable exam grades I had!
My earliest concrete memories was from when I was two years old, and I remember quite a few things from around that age. And no, they are not from pictures since I remember domestic arguments and fights between my parents, and I know it's before I was 3 since my mother left the country when I was 3.
