I got home today and found out that my roomate Will pulled An Uncle Fester, he cancelled our Internet service without warning because he has a gambling addiction.
Uncle Fester is at it again, he took all my laundry out of the dryer and through on the top of the dryer because he has to do his laundry at the same time I do mine.
