My sister-in-law and one of her sorority sisters lived in a dorm that housed three girls per room. One semester, they ended up in a room with a girl who didn't like sorority women and claimed to be a practicing witch. They would often come in and find her sitting in the lotus position, burning incense, playing eerie music and seeming to be in a trance. She would freak out whenever they "broke" her trance.
The three just didn't mesh at all and it was tense. One day SIL and her sorority sister came in and saw that the third roommate had left her journal out in plain view and wide open to that day's entry. SIL said she knew it was really wrong to do so, but they read the entry for the day. It was kind of staring at that them from the desk almost like the third roommate wanted them to read it.
"I still hate living with Sarah and Judy, the sorority princesses," the entry read. "BUT they have been much nicer to me ever since I cast the spell on them."
The other two had a good laugh, but started making arrangements to move out as soon as possible.
