He admitted being a paedophile
It seems texting is easier than talking face to face, but it's so easy to fuck up a nice conversation by accidentally sending something you didn't intend to. This guy made a terrible mistake. He was getting to know a girl. Both of them loved One Direction, so they often sent a lot of links to various fandom things they saw on Tumblr. Of course, the boy sometimes read other stuff as well. Once he read an article about a paedophile who never acted on his desires.So he accidentally sent this article to the girl. His caption for the link was "I feel exactly the same way."
