I hate that Guy!

One of my colleagues always wanted to touch my nose, I don’t know why he have to do that… my nose is not that long and not too short or pointed its only a simple nose not flat not pointed but its fine. This afternoon, when I told them if they have no more concerns or anything regarding their duty, they can leave my room already because I have to attend for an important meeting with other company. When suddenly this guy always looking at me and smiling at me without any reasons that’s why I’m always asking him if there’s something wrong? He answers me back only for 'nothing'. Then I told him that he may go now because somebody is waiting outside, but then before he left he started to touch my nose and then he smiled and walked faster because he knows that I might get angry again, but it happens all the time. That is why I hate that guy!!!
