My Friend's Female Friend Likes Me?

[Levi]

I met this girl who's a friend of one of my friends last week. She spoke mostly with her friend mostly and me very briefly.

YTuesday my friend went to go see her and they spoke most of the time. Me and her talked a little when he was doing something.

I then told him I had to catch the metro and his friend said she'd take it with me. We spoke about different things until my stop. Wednesday I woke up and have a friend request from her on Facebook. A Good sign?
