well i asked a friend out i guess, but i only knew her for 2 months or so before hand...things are good now but i hope we stay close when the inevitable happens...which it will
i think it can be good, but if you let things get to the friends stage it becomes more hard to actually get her. i tend to have a disposition towars the friends thing, and hope she develops feelings....and decided not too with this girl and it worked.
so i'd say if you are interested in a girl, make a move quick, and if you become friends then go for it...if you break up amicably there's no reason you still can't be in each others life
