**So some revelent background information before I get to the meat of the matter:**

My sister is 18 yo and is in her first year of university. She went pretty wild her first semester and is looking to pledge for a sorority next semester. She asked my parents if she could go on a cruise to mexico with her friends, they told her no, she said okay and that conversation was over.

**What happened:** 

She posted some drunk photos  of herself topless in Cancun, Mexico, on Instagram. The location name was embedded in the photo on the top.  One of my friends, who follows her, sent me a photo of her saying: "Wow you're sister really went crazy her first year". This was about an hour after she posted it. I did some digging around and apparently she had mentioned to one of my friends that she would be going to mexico, about a week ago. Also apparently a lot of my friends follow her on instagram.

**The Snitching:**

At this point I'm very confident she indeed is in mexico. A couple of things run through my mind: 

1. She's with a bunch of older guys she's known for less than a semester.
2. My sister is easily peer pressured and will go to great lengths to fit in with whatever group she's hanging out with.
3. No one fucking knows shes in Mexico. 
4. She has mom's credit card.
5. She drinks a lot of alcohol and gets drunk very quick.

I found myself in a very uncomfortable spot. If anything happened to her (getting taken advantage of, alcohol poisoning, getting in trouble with the law, etc.) I would be partially responsible, since I knew where she was and didn't let anyone know. On the other hand I'm one of the few people she confides in and trusts, and also her brother *(I'm 22 yo, we're 4 years apart*).

So I spilled the beans to my parents. Lots of punishments are on their way.

**AITA?** 

&amp;#x200B;

Should I have minded my own business? I'm always  true to my word and I've never spilled a secret someone's asked me to keep. Even though she never shared her intention to go to Mexico with me, I know she will feel betrayed. My sister's relationship with my parents is already kinda shaky, will this just drive her away more? These are the thoughts I'm wrestling with.

&amp;#x200B;

I know for sure there could have been a better way to handle this. I am not proud of my decision nor do I think I know what's best for her. Thank you for reading.
