Walking a girl to the Parking Lot?

I had a night class tonight, when it ended, a girl asked me to walk her to the parking lot. May this mean something? Or was she just looking for someone to escort her? Generally, Girls tend to be scared of me, so this really threw me off.

I think the girl did like me, but I messed it up. I was in class early and she was the second person to walk in. She smiled at me ear to ear for a solid minute the we spoke for a bit. he said " I don't want to sit in the front row today." and began walking around slowly. (I was in the back...alone.) I, for once, caught the hint, but was to nervous to act upon it...
