So for context I 18(f) and my sister 16(f) got into an argument because I didn’t close the bathroom door all the way after I was done using it so when she got mad at me and destroys my book because i stepped on a huge pink rug that takes up the entire floor in our shared bedroom and I got it wet cause i just came out of the shower and was changing she comes in and yelled at me for not closing the door and so she runs over to my bookshelf and takes one of my books (that I paid for myself) and ripped out the pages so I got mad at her and you know when you give some the “L” and stick out your tongue? Yeah I did that and so she ripped the book, so am I the asshole?
