I sit opposite someone who I tend to get along with, although we're not friends. He went on annual leave and since he has come back he's been kicking the floor every few minutes loudly with his feet. Together with his insanely loud typing and loud eating noises, I'm going insane. Please tell me if it would be unreasonable of me to tell him to shut up?! I was murderous last week after a week of the bloody kicking.
