I was reading something on my phone, and my mom kept saying my name and I finally screamed "what?!" Which granted I shouldn't have screamed but I was reading, anyway her boyfriend was like that was fucking unnecessary and said I had no reason to act like a bitch and I told him he needed to stop and not act like a jackass. And he said "well see you treat everyone in the house like shit" and I basically started bawling my eyes out. I definitely don't treat everyone like shit and you're not my parent so you don't need to yell at me like that. Especially when we just bought you guys dinner and didn't even get a thank you for it. He's such an ass. 😒
