As a 6 or 7 year old girl, my mom was showing me what my birth certificate looked like. I was really fascinated by it, until i saw the word SEX and an F right beside this. For some strange reason, I thought this meant my mom and dad had been graded F (fail) for sex. I'm just really glad I quickly learnt that sex also meant your gender...
