I was doing incline bench press and standing next to the bench and looking directly ahead while resting between sets. A girl was wearing headphones and was walking back and forth in my line of sight just doing nothing. I glanced at her, she looked at me, I looked away. I then went to the water fountain on the other side of the room and she also came over, she said hello to some other guy at the water fountain. I went back to the bench and she started walking around back and forth doing nothing again. I glanced at her a couple more times, then another guy she knew came over and they dapped each other up. He left right away and she was still hanging out there. I gave her a wave the next time we made eye contact (she was wearing headphones) and I said "Do you need something to do (tone/expression probably conveyed that I thought she was acting funny), cause I could use a spot". She gave a little smile (think her expression meant she was surprised by the request/found it unusual but seemed a little excited) and said sure. I did 9 reps and she helped me with the last one and said "you got it". I let out a little 'woo' after the set and said thanks while I was getting up. After I finished she immediately moved on to the leg press machine, didn't even look at each other.

She wanted me to talk to her almost certainly right? No one else was in that area and she wasn't even looking for equipment or resting next to equipment, just milling about 5-8 feet in front of me.Did I open in the wrong way or maybe my voice/facial expressions weren't appropriate. I wasn't going to chase her once she moved on.
