I always have an issue with approaching a girl when is in the group. I don't mean bars and opening sets.

Recent example, near my house there is a hostel, where I see a chick that most likely stays there, but every time i see her, she is sitting with some older ladies, that are workers of that hostel and they usually sit around the round table outside talking. Closed circle.

I really wanna approach her and talk to her, but it will be extremely awkward for me to approach that round table and start talking to her.

How should I do it? I caught myself looking out of window pretty often to notice that she is alone and rush out to meet her. But i'm really embarassed myself about that wish xDD
