<human>: Hey Reddit!
So recently I went to perform with other high school juniors and seniors at a concert, and I met this really cute girl, but unfortunately, I did not have the balls to approach her in person and talk to her (yes I know and I regret it), and instead just kind of gazed from afar. 

After coming home from the performance, I found her on Facebook, and friended her. She accepted my friend request, to my surprise, because I thought she didn't know my name. Anyways, after scrolling through her Facebook, I realized that I really do like this girl and I'm hoping for a relationship with her.   

Anyways, I know I need to at least strike up a conversation with her to have anything of a chance, but I have absolutely no idea of what to say, considering I didn't even think she knew I existed. I guess my question is what should I say to her over Facebook without ever having talked to her in person before?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Met a really cute girl, didn't have the balls to talk to her, regretting that decision, now don't know what to say and how to say it over facebook (with the ultimate goal of getting into a relationship?)
