1. Taking pictures the entire show: I get it. You want to show all your friends on Facebook and Twitter that you were at the concert. Fine. Take a photo. Take five if you want. But please, don’t take 1000! You always manage to hold your camera right in my line of sight. You don’t even look like you’re enjoying the show while you’re doing this. All your attention is on the pictures you are taking. And you know what? Those pictures are all going to look like nonsense, every single one of them. You’re too far away from the stage. You’ll probably never even look at them. Also, you see those guys right in front of the stage with the giant cameras? They’re taking great professional pictures. There’s really no need for yours.
