Is NOBODY wrong in the post ? POST : Despite the stupid title, there's actually a bit more backstory.

&amp;#x200B;

I'm 13 years old, and my sister is 17. 

Her school is done, so she stays at home for the whole day. One day I come home at like 5pm from the bus (parents work quite late and don't get back until about 6:30) and there's leftover pasta from the night before. She's already eaten her dinner and I'm about to serve myself. I scoop one scoop and then I'm about to do another (i need lots of food), and then my sister chimes in saying stuff like "you don't need another one" and "save it for parents". normally this wouldn't be a problem, but she says it in a shouting  way  and this kinda ticks me off a little bit for some reason so I jokingly keep on serving the second spoonful (i was gonna put it back) but then she runs up to me and starts grabbing my arm and pulling me away. Like idk why but when someone gets really angry at me for little to no reason it annoys me so I push her away but then she gets really angry and starts punching my arm. She takes the pasta away and says 'you don't deserve it and stuff.' The punching doesn't hurt but I'm kinda annoyed now so I push her really hard. She starts crying and going on about how 'im stronger than I think' (which is an excuse she uses 24/7 with parents) which is kinda true. I'm kinda pissed off because when my parents get back they would take her side of the story because she's older and she sucks up. She tries retaliating but I don't quite remember the next few minutes but its basically back and forth physical fighting, but in all, she definitely punched/kicked more than I did. I did use a few choice words and punched/kicked as hard as I could though. I generally kept my calm. Parents come back and surely, after debating and the like I get in trouble. It doesn't end here though. I still feel like I was wronged so I wanted to kinda get revenge so I walk into the kitchen and take the leftover pasta and say really loudly "oh I wanna eat this pasta" and then she gets angry and another fight brews before my parents can stop. I kinda feel like I could've done things to stop it but Imo its generally my sister's fault. Am I the Asshole?
