Bieber calmly and politely responded to this fan commment -- "You're such a prick. Your fans are the reason you are as successful as you are. The least you could do is take pictures with them" -- explaining how the demands to pose for pics had become overwhelming.

"If you think setting boundaries is being a douche I'm the biggest douche around but I think it's smart and will be the only way I last. I wanna enjoy life and not be a slave to the world and their demands of what they think I need to do!! I love the fact that I am able to make people happy but cmon if you truly were in my position you would understand how tiring it is ( boo hoo Justin get over it) I'm going to keep making decisions I feel are fit for my growth and no human being will make me feel bad for it."
