I used to believe that all babies (boys and girls) got circumsized. once i heard a classmate talking about babies being circumcised and he didn't specify whether it was boys or girls so i went home and asked my mom one day if i was circumcised. "She replied, only boys get circumsized junie." "hmm, didn't know that" I replied. well, now i know.
