All girls like a confident lad. As long as you are comfortable with yourself and don't try to act like someone that you're not. My fiance didn't dare approach me when he first saw me in a bar coz he thought i would laugh at him, but a couple of hours later he came over to me and i was impressed that he had built up the courage to speak to me. The most important thing is to not be sleazy, as us girls hate that! Presuming that u r old enough to drink is u r out, the first thing u could do is offer to buy her a drink, ask her what her name is, where she comes from etc......if u click with that person, you will find that you won;t even have to worry about talking because the conversation will flow naturally!
