Really pisses me off my oh goes out straight from work and doesn't even tell me, obviously he doesn't need my permission but it would actually be nice to be fucking told, especially when he told me he'd be straight back then not even half an hour later I bump into one of his friends and he tells me that my oh asked him to go out after work
