My friends MIL(who is also her phupho cuz she married her cousin) walked into their bedroom on their wedding night when they were half naked and stood there and talked to them while they scrambled and tried to cover themselves with the comforter. I think the door was locked but then she knocked and her stupid husband opened it without dressing cuz he thought he would just listen to whatever someone was saying and close it again but the MIL just opened the door wide open and walked right in.
