"I was 13, hanging out with my friends all day, every day. At some point, this guy started hanging out with us. I don't know who he was friends with first, or where he came from - one day he was just there. His name was Shane. Shane looked a lot like David Schwimmer...if David Schwimmer had more acne than bare skin... and was the product of generations of inbreeding. Shane said he was 16. Shane started hitting on me pretty heavily. It got to the point where I couldn't hang out with my friends, because he was constantly there, and constantly saying gross things to me (telling dirty jokes about himself or describing himself sexually). What's worse, my friends kept trying to get me to accept his advances, because it wasn't like anyone else was interested in me :("
Then he became friends with my brother, and would come over to our apartment frequently. One night, I came home to find him sitting on our couch next to my mom. She said he'd said he was a friend of mine, and she was showing him baby pictures of me, class projects, etc.
So... it actually just stopped about as suddenly as it started. He just disappeared one day. That is when I found out that when he would be in our apartment with my brother, he would mostly ask my brother about me, and my brother frequently let him into my room. He went through all my papers, looking for some mention of him, apparently. He also broke into a locked book he thought was a diary.
Also, he was not actually 16. He told my brother he was 19. Right before he left, he changed the number again - to 26."
