Woman Comes Home Early, Finds Sister and Boyfriend Basically Living in Her Apartment

A woman who travels for work about two weeks every month thought she was doing something simple: giving her little sister the keypad code so the plants got watered and the mail got grabbed. Instead, she came home a day early from a trip and walked into a scene at 11 p.m. Her sister’s boyfriend was on the couch. Her sister was wearing one of her hoodies. Their bags were in her bedroom, and the bed clearly hadn’t been slept in by only one person.

When she asked, her sister admitted it: the couple had been staying at the apartment most weekends she was out of town. The woman told them to leave that night, and they were gone by 11:30. By the next morning, she’d changed the keypad code. Her sister responded by saying she’d been humiliated and hasn’t answered any messages since. The post on Reddit’s r/AITApod racked up over 6,600 upvotes and 1,100 comments, with most people firmly on the apartment owner’s side.

The whole thing comes down to one question: does giving someone a key quietly mean giving them permission to live there? Most of us would say no. Trust isn’t a lease. So what would you have done in her shoes?
