How do i talk to a girl i like?

How do I talk to a girl I like but we dont know each other?

start simple like hey or whats up
then gettin to know eachother like what you doin this weekend?
make sure she's interested in you first.
open doors for her, compliment her, don't look at her body, look into her eyes.
its what every girl wants.
somebody mature, not a boy.
good luck

I agree with lame0
find something she dost a lot.
for instance

this one boy notice I txt a lot in class
so one day before class he came up to me and asked what classes are easiest to txt in. and we started to talk...a lot.

haha after class I gave him my number and now we are always txting.
