<human>: Just found this subreddit today and thought I'd share my own story (Not sure if this belongs here but whatever):

This was awhile ago when my Sister and I were young kids. One day, we get into arguement at the dinner table (You know classic, childish name-calling for no apparent reason). Anyways it gets pretty heated and we she starts screaming all kinds of obscenities and curses. Finally she jumps out of her seat, runs out the room yelling, "I hate you sinbad-ass! You're such a bitch of a brother!" (I know, Kids say the darndest things). Anyways, thinking she got the last word, she dashes up the stairs but moments later everyone in the dining room hears a loud thump, followed by the sobbing of my sister. I'm overjoyed! I get out of my seat, run up the stairs, passing my sister saying, "How do the stairs taste, Sis?" I'm a hero. I hear my brothers and my dad laughing hysterically and even my loving mother getting a few chuckles in. One of the greatest days of my adolescent life. Oh, and she got grounded for calling me a bitch!

Can you summarize the given text in a few sentences?
<bot>: Me and my sis argue, she calls me a bitch, runs up the stairs and trips, everyone laughs at her and my comeback, she gets grounded.
