ok i found two problems with that statement :p.
1. we all know girls wont ask a guy out (i know this freakin sucks)
2. letters are the worst thing ever
if your gonna ask a girl out. just man up for a minute and ask her. if she says no... then thats too bad... life moves on and you'll find another
i usually get a good friendship goin with a girl before i make any moves. if i really like her then ill continuously give her nice compliments and sweet talk her. i will do this until she wants to go out with me. once im certain she'll say yes, i ask her out. its a simple process but can be pretty long sometimes.
