Emma definitely has a good point. At the beginning, my student would only ever come to my office with a question. When you are in the middle of a testing problem yourself, it can be quite stressful then trying to change your thoughts to another problem. However, now it is a lot better as my student will now wait till a few problems have developed and then arrange a meeting. In the mean time, my student often comes by my office to talk about conferences, and various other things not regarding the PhD. It's become a much better relationship all round really.

I've worked with a number of supervisors over the years, and now have my very first student. As long as you show enthusiasm and and a willingness to learn, your supervisor will respond to that. Although from speaking with some post docs, they often don't like having students, but feel they need to in order to further their career. That scenario is a hard one to work with.
