This Girl Is Just Being Friendly Right?

[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.

Yesterday 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 then spoke about different things until my stop. This morning I woke up and have a friend request from her on Facebook. A Good sign?
