my friend moved in with me a few years ago and we have a really full house with 5 kids and only one mom. we have a tv in the living room and literally every single time i'm watching tv with my sister, he comes upstairs and sits silently at the table and eats. and he doesn't say anything he just sits there and listens to our conversations. the only way he'll go downstairs is if we go back to our rooms. it reallyyyy annoys me and makes me feel like i don't even wanna watch tv cuz he comes up every time!! anyways i guess he's just lonely but it's rlly annoying

TL:DR aitah for wanting to tell my friend that moved to stop intruding on my time with my sister?
