I had a roommate who would go into screaming meltdowns until the GA had to come in and shut her up, accused me of "stealing her best friend" when she barely knew the girl in question, and once locked me and said girl in the bathroom when we were dying my hair until I threatened to break the door down. I was singing the Hallelujah Chorus the day she finally moved out.
Story 2 regarding the woman with disabilities. I totally relate regarding needing the door locked when being home alone because I also have disabilities and have no way to protect myself. However, everything else was over the top, unreasonable and she sounds like she may also have mental problems to go along with all that. Yikes! My ex-roommate refused to lock the door or let me know when he was leaving so I could lock it, no matter how many times I've asked and told him that it was for my safety and peace of mind. The reason why he didn't want to let me know is because he didn't want to "report to me" on where he was going. I didn't need to know where, just so I can make sure the door is locked. He would lock it if his kids were going to be home alone or he left the house when no one was there. There were many, many other issues with him, but this is related to that specific story...
