A girl I barely know added me on Facebook. Does it mean anything?

On Monday, I met this girl for only, like, three minutes. We only introduced our names and talked briefly about school before I had to excuse myself to go somewhere. I almost completely forgot our meeting. Then, today, she friend requests me on Facebook even though we barely met and she apparently rarely uses Facebook (only 16 friends, very inactive Wall).

I told one of my friends and he says it means she likes me. I don't want to assume anything though since I barely know her. What do you think?
