Hi everyone, I wanted to see if anyone could help me with this problem. I've been going to a few parties and I usually find myself in a situation where there's a girl who seems to be interested in me but she's usually with a couple of her girl friends. If she was alone I wouldn't have any problem talking to her, but I feel that the same approach wouldn't work if she is with her friends. If anyone could help with how to approach her and what to say I would really appreciate it!!
