A Reddit reply
“AITA for asking my sister to stop dropping by my house unannounced? She has a key for emergencies. Lately she's been showing up with her kids and staying for hours. I told her she needs to text first. She called me cold and selfish. AITA?”

Here's a suggested reply: NTA. Having a key for emergencies doesn't mean having an open invitation to treat your home like a second living room. You're not saying she can never visit — you're asking for a completely reasonable boundary: a heads up before she comes over. That's basic courtesy that most people extend even to close family. Showing up unannounced means she's deciding for you how you'll spend your time. You're entitled to control your own space and schedule. The fact that she called you "cold and selfish" for asking her to text first is a pretty big red flag. That's a guilt trip designed to make you back down.

nta. emergency key ≠ open invitation to your house whenever she feels like it. asking someone to text first is like the most basic boundary possible. she's making it dramatic because she knows she's in the wrong.
