Lol. You are asking such a good question! Most girls just wait for guys to come up and chat to them I guess... with that in mind, you could make it easier for them by seeming friendly. You could chat to guys - I like that and I guess most people would! The other day, a girl came up to me and spoke about my T-shirt which was a good starter, and I think it's the nicest thing when you are dancing and someone just looks at you and smiles - it's nice, not aggressive, and would make me want to talk to them. Having said that, I'm rubbish because I always get shy when I want to go up and talk to new girl. Sucks.
