A new guy has started at work and his personality is somewhat challenging. A conversation with him is like being run ovrt by a bus. He just talks at me about stuff I am not interested in. He comes up really close to me when I am trying to work and starts talking so I cant concentrate. HE IS REALLY irritating. Its a weight off my shoulders when he has a day off. He does not read my subtle hints so i have to resort to being rude to him or avoiding him. AIBU? How do i tell him to back off and shut up... in a polite way?
