Meeting with Supervisor after three Months..;-)

Tomorrow I am hopeful of catching up with my PhD supervisor as he is visiting his home institute for two days. I met him in the first week of August, since then there were around 15 email exchanges between us related to various stuffs. Although he managed to give couple of useful feedbacks regarding my paper (which I have recently submitted to PLB) , I am not being able to work much towards my next paper. I always feel, I need to do lots of live discussions to clear doubts and move ahead which is hardly a reality. And my supervisor is so busy with non-academic activities that he hardly replies to my mails. Sometimes I get replies to some mails sent around two months before. I do not think I am smart enough to carry on my research like that. I always feel like communicating this to him, specially from next semester point of view. This semester at least I am finishing my coursework although not being able to do much research , but in the next semester I have no purpose of staying in the campus if my supervisor is not here. The problem is that he is going to McGill on sabbatical for the next semester, which again gonna screw my research. I have spent two semesters already here in the campus (autumn 2008, autumn 2009) without much progress in my work as my supervisor was in a different institute. I just do not want to make such a repetition in the next semester. It's two frustrating to spend days without any useful work. Let's see what happens tomorrow, just keeping my fingers crossed.
