I work in a small office and as a result have to interact with said colleague mostly everyday. Whenever we are alone, which is quite a lot as we share the same room, he wants to chat me up. He brings up topics of religion, politics, food habits etc, and though he lets me speak my mind he has this habit of reacting after almost every sentence. It seems like it's his personality to question everything.
I'll give a small example:
Him: Do you want sugar in your tea?
Me: No.
Him: Why? Do you have diabetes?
Me: No, I just don't want to consume a lot of sugar and I like my tea sugarless.
Him: Oh! (Makes a weird face)
I am not intimidated by him, but I wouldn't want to cross the line with him either. I have tried to avoid any conversation that's not work related. But at the same time I don't want to be rude. It's a small office and I want to get along well with everyone.
Any suggestions or personal experiences?
