First off, I'm on mobile so sorry for the format
This is a short one

Now my sister is a bit of a bitch to me so I wasn't really surprised but I'm curious.

I was on the couch watching TV and she came up and said I was sitting in her spot, I didn't move so she sat ON ME (I'm a guy so this was weird), I got pissed off and told her to move, I tried pushing her but it didn't work. I had an open water bottle in my hand so she decided to tap it, my whole right side got soaked, so I got really PO'd and poured it on her head, she proceeded to yell at me and called me a dick. She changed clothes and for the rest of the day, she called me an asshole.

So AITA?
