Having roommates is a very important step in the human maturation process. It's on-the-job training for any future marriages, discovering your annoying habits, and realizing that most people are pretty difficult to live with. You're not. You're never the problem. It's those stupid roommates that need to realize you're perfect and never do anything wrong.
This is why so many roommate fights tend to start with notes left around the apartment. Rather than dealing with the problem like a mature adult, roommates love to leave cute passive-aggressive notes around the house that only make things worse. If you're currently having a roommate problem, we feel bad for you, son. Here's some pictures of funny notes from roommates, so you won't have none.
