Hi guys, hoping someone can give me advice on what I should do to game this girl.

There's a really attractive ex-schoolmate I've noticed since I was in college. It's been 2 years since graduation. She knows who I am, and I know who she is as we've seen each other around school. Once she happened to take my order while she was working at this fast food place and she acknowledged with a smile and 'hi' and I did the same. Other than that, I've never talked to her before.

Just this week, I followed her Instagram and thought she became even better looking than before. Apparently, she just broke up with her boyfriend on 20th May 2013.

I figured that it's very unlikely that we'll bump into each other outside, and so the only way I'm gonna be able to start talking to her is through Facebook message. How should I open the conversation (hopefully minimal awkwardness) and do I go indirect or direct? It'd be appreciated if someone could teach me how to progress it to asking her out as well.

This is quite a long shot. If i thought i had a chance with every girl who ever said hi to me, I wouldn't be able to sleep, hell, I wouldn't be able to even zip up my pants, or wear any! Why don't you just friend her on facebook as a start. If you are already facebook friends, when was your last communication with her? If it was during college, like 2 years ago? Jeez, good luck. I'd open with something like "Hey, funny thing, ran into a random kid/girl from college and he/she mentioned your name, how are you?"
