Guys and gals please.?

in college today, no idea if was a joke on me or whatever. Basically im not the best looking guy around, nor the funniest or talkiest/chattiest.So anyways, i robbed some girls computer (mistake ofc), and she came back, i said sorry is this yours? she said no its fine. coz she was moving. 10 min or so later a friend of hers came back and said the other girl wanted my number? ok, this is new, gave it to her. basically im totaly crap with this thing. so she asked if i wanted hers? i said no, i'll wait? for some very odd reason, (dont know myself). (i was blank for majority of this rofl) so when we finished, i turned round and the one who came for my number (her mate) was giggling :(. when they left they said ''byeee ''. So you think this was just a wind up/pizz-take? or what? i dont know. im 18 and i completly suck at this kind of thing lol.
