So Quiet
After reading all the crazy stories on this list, this particular roomie doesn’t sound that bad, to be honest. Apparently, he introduced himself to the OP when he first moved in and hasn’t said a single thing in the six months that followed.
Sure, when you move in with someone you expect to build some sort of friendship as time goes by. However, not all people think the same way and frankly, that’s okay. We’d rather have a flatmate who’s an introvert than someone who is creepy, steals stuff, says he’s possessed, or tries to harm you in any way!
