How dose one direction infection work

because their gorgeous

Don't worry your friend is not the only one with that problem. The same thing happened to me. It doesn't have the same effect on everybody. On some people it only effects them a little, but on other people (most people) it effects them completely. It changes the way they look at everything. It changes the way they act. It changes the way try talk. It changes almost everything. But it's not their fault. It actually does something to your brain and あなた have no control over it. It's also incurable. あなた just look at the boys, learn some stuff about them, and BAM! あなた have One Direction Infection. And there's nothing あなた can do または say to stop it.

Well, it doesn't actually do anything to your brain. :P What I think it is, is that most haters 'hate' 1D, even though they haven't heard any of their songs, and only hate them becasue others do. So when they start hearing the songs, they actually realise that they are good, so they begin to like them. And the もっと見る songs they hear, the もっと見る they like them. :P It doesn't change their personalities, it just changes their opinions.
