You ignore your friends
Let’s face it: 95% of the reason single people go out is to meet somebody. There is no shame in that. But, at the same time, there is. If you’re completely ignoring your group of friends and instead scanning the bar continuously, eyeing everybody, you look desperate. Meanwhile, a man who is engaged in conversation with his friends is far more attractive. He looks passionate about something. He looks like he values his friends. He looks like he’s just there to enjoy the night. Don’t be rude: talk to your friends that you came with. The less you look around for women, they more they will come to you.
