Is OTHER wrong in the post ? POST : **(WARNING: Contains multiple angsty f-bombs.)**

So, I'm a 13, almost 14-year-old girl. My half-sister is 24, and we'll call her L. My dad is 55 and his GF is 54 or 53. Now that we have the ages out of the way, I'll get on with the story.

Some background: L is my mother's daughter, and not my father's. They do not get along, as our/my parents are divorced and L has made some choices my dad disagrees with. L also has a three-year-old daughter.

So, my dad, his girlfriend, and I went to a football game. My dad had noticeably drank a lot and was slurring his words. His gf sees nothing wrong with it and he decides to DRIVE us to my sister's workplace, a restaurant with a pretty nice bar. He orders a single drink and we sit down.

Of course, I want to see my sister - I saw her car in the parking lot. I ask one of the waitresses if she can wave her over, and soon enough, my sister comes over. She greets us and is acting as sweet and as respectful as she could.  We talk a little bit and she asks me if I could see her before we leave. I don't see anything wrong, and neither do my dad or his gf, and I agree. My dad is still slurring his words, and once we finish eating, I walk to the to-go area to say goodbye to my sister.

She suddenly hugs me, warning me that my dad is drunk beyond belief and that she wants me to text her when I get home to my mother's to make sure I'm safe. She's seen my dad drunk (and I hadn't at this time) and was extremely concerned. She had talked to the other employees about it, but they couldn't cut him off because he had only ordered one drink at the establishment, and while he was showing red flags, they couldn't do anything about it due to their policy. I agree to do so, worried, and I head back over to my dad's table.

I said something along the lines of, "Dad, I think you're a little drunk. I think it would be safer for us if \[his GF\] drove instead." Now, keep in mind, this was entirely my idea.

THEY BOTH GET PISSED. His girlfriend starts angrily blaming my sister for *something she didn't even suggest.* She walks to the middle of the restaurant where the entrance is and starts demanding to see my sister, and I try to calm her down and say that we should leave. My dad is silent this entire time. His GF starts to yell about it, and after pretty much dragging her out of the restaurant before my sister caught wind of it from the other side, GF starts going off about stuff that she doesn't fucking know anything about. We also almost threw hands. A thirteen year-old. AND A GROWN FUCKING ADULT.

(From here on out, I'm pretty biased and still pretty pissed.)

So, I keep pushing the idea that she should drive instead of my dad. She gets mad and claims that my dad "has barely drank anything" and that "he wasn't drunk", which *he obviously was*. She then starts saying my sister "doesn't even know how to raise a child" and that "she needs to get her fucking life together before she comes in here spouting lies". Lemme ask, what the *fuck* does that have to do with this??? This was her first time meeting L, too.

She goes on and on about how horrible of a person my sister is as my dad gets into the driver's seat and I into the back. Now, I cry when I'm angry, and that's what I was doing - I was pissed beyond belief and couldn't just tell her to stop because then my dad would get mad at ME for being "disrespectful" (as he did later on anyways.). I refused to speak after one particularly rude thing his GF said to me, and I stayed silent until I get back to my mom's.

**TL;DR:** My dad got drunk and we went to my sister's workplace. She stated he was drunk and was worried about me. I told my dad that his GF should drive home instead and she was pissed off for absolutely no reason. We get in a fight (almost a fist fight) and we leave. They got mad at *me* and my sister for trying to be safe.

**AITA for getting defensive of my sister?**
