Not my problem

I hate you for having the nerve to ask if your 16 year old son can live with me and my boyfriend 5 out of 7 days per week. Ummm no, actually that is not okay with me but because you are my boyfriend's fucking moron sister, the boyfriend cannot say no to you. Can you even fathom how much of an inconvenience that is going to be? We work Monday to Friday 9-5, school is generally held at the same time so when we are going to be getting home so is your damn son, I guess I can look forward to no privacy. We will have no time together. I am a smoker of the herb and since the last time your punk ass smelled weed on me you ran to your mommy to tell her, I have a feeling that this living arrangement is not going to work in my favor. Am I an asshole for saying to my boyfriend that he has to say no to his sister or I'm outtie? I don't think it's ridiculous to say that occasionally he can stay, but for a young couple (25 & 27) having a 16 year old there all the fucking time, is not gonna work. If I wanted a roommate, I would find one... one that I like, and one that pays some money towards rent. Fuck I am so pissed off and frustrated. I don't know what to do. I want to scream, cry and punch things all at the same time. —Take care of your own fucking kid
