My son endured a full quarter (10 weeks) with the roommate from Hades. Drunken fights, threatening people, got put on probation (not a strong enough punishment IMO), and then his mother suggested he tell the school he was depressed and that is why he was in a fight, so he took his exacto knife and cut his arms 16 times, laughing all the while and saying, "This should make them think I am depressed!" There is more, but you get the gist. He was a nightmare!
He was home last week for Spring Break. We just took him back yesterday, with all of his stuff, to move into a new place, apartment style, with his own private bedroom. He FINALLY agreed half way through last quarter to let his college know he has Asperger's and needs some accommodations! It took them this long because they were full and didn't have anything available for him until now.
However, he did great, ended strong, kept his scholarship without a problem, and is going back for Spring quarter!
