Will it be awkward?.. Im interested in this girl..

I am interested in this girl for a while now but nothing has really happened, except a couple times we walked past each other and smiled or said hi. One of my friends keep telling me to add her to facebook but that would be creepy. Btw i got her name from one of her friends, a guy. Anyway i found out recently she is on Twitter, and i was thinking i could follow her to see what happens, but still i think that would be weird. I can't think of how i could introduce myself in person... Help? Thanks!

If you are interested, find out if she has a boyfriend. If not, ask her out. It's that simple.
