Hi all, I wanted some advice on my research-advisor. I was fortunate to have enjoyed a nice night in town with my research-advisor and his girlfriend. He insisted on paying for everything, and he did. I was quite grateful, and have been wondering about a way to return the favour, and/or conduct myself with gratitude (short, of course, of groveling). He is a quiet extremely reserved man with a fastidiousness that seems to have served him well. I was floored when I found out he held two-year position at the Institute for Advanced Study. All I could find out was that he enjoyed the soundtrack from the movie "King Arthur", and that he went to go see an educational IMAX film about research on the dinosaurs. I am thinking about asking his girlfriend what his interests are, so that I may present a fairly-thoughtful token of my gratitude. However: I'm notorious for stubbing my toes on social taboos. Anything that I have not foreseen, or may be doing wrong?
