<human>: Condense the text into a few key points

So I lost my ID last night after going to a bar (I believe it was lost on the cab ride home) and this morning I receive a message on Facebook from a girl saying she found it and if I'm still looking for it to come to her dorm since we go to the same college (she also ended the note with a smiley face). I assume she did some FB "research" before contacting me but I'm not sure if this was because she possibly finds me attractive or this was done out of pure generosity and kindness. In my experiences in life I'd find it unlikely for someone to take such effort just for the latter reason, but that's just my experience. She is fairly attractive and I'm trying to decide if I should simply get it back and thank her or if i should try and work something out of this and offer to thank her by taking her to lunch or something along those lines?
<bot>: Cute girl finds my ID and offers to return it, is this an act of random kindness or do I try work a date out of this somehow?
