<human>: I've never been that confident around girls. However the other night I was at a concert and I was having a good time and it started getting hot so I rolled up my sleeves. (I work out on a regular basis so I'd say I'm somewhat fit) anyway I'm all dancing and I feel a girl behind squeeze my arm right after I rolled up my sleeves and I was flattered so I turn around and she points to her friend they are both pretty cute. But I just laughed it off and squeezed her arm too however I didn't know how to take it from there I was scared of doing something back that would make it seem creepy what should have I done?

Can you give me a shortened version of the text?
