I have been trying to not limit myself with mixed sets. Reason, they dominate the bars I go to. The other day, I saw a girl who looked bored so I walked up to her while another dude was talking to her friend and she was completely shut off from the conversation and no attention was on her. I went into entertain her and said "you look bored, whats wrong." She started to tell me and he cut her off and said to her "don't talk to him", I tried to introduce myself to the guy by asking what his name was and offer my hand to shake his. He smacked mine and said **** off, I was about to beat his ass. What is a better way to handle this?
