When questioned by his parents his answers were fragmented and unrelated to the questions. He was an avid Trivia player and looked forward to meeting his friends weekly at the local tavern for Trivia and a few beers, but recently has has not been showing up. When contacted by his friends, he rarely responds, and he is aloof and withdrawn. His parents also noted that he no longer seems to care about his hygiene or appearance.
