When I was young I used to hear about teen pregnancy where the girl would say "I never thought it would happen to me." I didn't know you needed both a boy and a girl to get pregnant at the time so I was always worried I would just "become" pregnant when I became a teen, like those other girls did. Because I didn't think it could happen to me, so therefore it probably would.
