Answer 2

I have a now former roommate who was thrown out by the live-in landlord and now, out of childish retaliation, he went to the post office and had both of our mail put on hold. They gave it to us but he signed a form stating that he was moving out, and wanted all the mail in the household to be put on hold. Do I have a case against this jerk?
