I'm a Hugger

One time at school class was close to an end, so the teacher let us all play Truth or Dare. One girl dared me to go into another classroom and hug a random person. I got up and went to do so, and she followed me to make sure I would go through with it. I walked into a classroom, went up to this random guy, and hugged him; after a moment, he hugged me back. I saw the girl who dared me and she looked shocked. I then left without a word to anyone. Back in our classroom I saw the girl talking to our teacher and I went over to see what the deal was. The teacher then turned to me and explained to me that the boy I had hugged had been in an accident a year or two before and couldn't remember any of his life before it.
