Okay, so I friended this girl because her network said "harvard" and because she looked cute.
(in response to her question "hey, who is this" on my wall)
me: well my name's above... a little towards the left, you know, next to the picture

my thoughts: because she added me back after I sent the friend request
her: lol well hello o:
me: wait...you're not one those creepy stalkers that accept friend requests just because the other guy looks good..are you? lol
her: are you implying that you look good? haha. and no.. i saw we had mutual friends
me: haha. for someone going to harvard, I would think she would know there is no need to imply the obvious [ you set yourself up for that one

]
my thoughts: maybe I shouldn't have added "[you set yourself up for that one

]" at the end?
her: haha. quite humorous, i see
my thoughts right now: uh-oh....this sounds like she is getting cold...or creeped out.
I feel like I'm getting put into a shit test or she's putting me off with her last line. It feels awkward for her to say: quite humorous, i see. How should I respond?
