I used to do a similar kind of thing and in new situations and new people, I sometimes still do. Especially if it is a new or unfamiliar job. People get hostile and aggressive about it, and having some awareness of social convention, I tend to draw back and avoid too much interaction with them.
The last job I had, when I first got there, somebody would say something and I would ask 'Why?', if I didn't understand why they were asking the question. I was doing it to try to get more information out of them but I was told that I kept on asking too many questions all the time, and also challenged because I kept on bringing computers into every conversation. They didn't talk about anything interesting. In fact, they didn't talk about anything at all really.
It used to be far worse when I was younger, but now I am much more aware of social convention it tends to be less of a problem. As I do not want to be shaped and patterned according to their requirements, I just keep myself to myself and not say anything that will give them an excuse to keep me out of their precious 'inner circle' (for inner circle, read 9th circle of hell like Dante).
