I have a few nicknames. Most commonly used now are Boo, BooBoo, and my older sister calls me littles.. (Don't know why I TOWER over her.But I will ALWAYS be younger. ) Boo and BooBoo in High School a friend and I used to always do a routine of Yogi and BooBoo with the teachers and principals and when I was little I used to hide a lot and come out and say BOO.
