As much as you want to approach with confidence, you don’t want to come off as conceited or rude. If she’s deep in conversation with a friend or listening to someone else tell a story, don’t just barge in and start talking over everyone. This also applies to when you are talking to her one-on-one. If she’s talking, don’t be the guy who interrupts her. Be the guy who is truly listening. That means making eye contact and not staring at her cleavage or hot friend.
