I (M14) and my sister is (19F).We both live at home with our parents. It’s spring break for me right now so I’ve been home all week while my parents are at work during the day.

A few days ago, my sister came home earlier than usual and brought some guy with her. I didn’t really think anything of it at first. I figured they were just hanging out or whatever, so I stayed in my room playing games.

But then like 15 minutes later I started hearing them from her room. I wasn’t trying to listen, it was just really loud. It made me super uncomfortable and I didn’t know what to do, so I just texted my mom and said my sister had a guy over and I could hear them doing stuff.

My mom didn’t respond, but that night they confronted my sister and it turned into a whole argument. She tried to deny it at first, then said I was being weird and overreacting. But my dad was just really quiet and my mom looked pissed.

The next day they told her she needed to move out by the end of next month. She was yelling and crying and now she won’t talk to me. She said I “snitched” and ruined everything.

I honestly didn’t mean for all that to happen. I just didn’t want to be stuck in my room listening to that stuff. I didn’t know it would turn into her getting kicked out.

So yeah AITA?
