My little sister is a bitch!!!!!!

My little sister is a fuckin bitch!!!!!!!!! When she tells me stuff bout her day, I'm suppose 2 care. When it's vice versa, she doesn't give a shit. I mean yesterday she literally said "you know I don't really care?" or "You know i'm not listening right?" That bitch!!! Or when i need to take a shower and i'm bout to step into the bathroom, she takes it and is in there 4 almost an hour!!!!!!!!!!!!!!!!!!!! She's such a pain in my ass!
