i think if you like it you should use it. i have 2 cousins who both have 'charlie's' one is a boy and one is a girl.. and they do see each other often! (i think one cousin stole the name off the other who had told everyone 'thats what i'm going to name.' before her bub was born, but she decide to still use it anyway. iykwim?)
that didnt really make sense... but i hope you get my drift
