I have just gone back to univeristy to do a masters in something I am completely passionate about. It's a good university and part of the experience should be the exposure to other interesting students. I'm not interested in the social side like an undergraduate - no interest in beery nights in the bar - but I am interested in stimulating conversation over coffee. But I already feel guilty - I have so much less time than other - childless - students and I really want to do well (I have my eye on a prize but can feel it slipping away already )I am torn. Do you say no to coffee after lectures? If I want that prize I'm going to have to aren't I? If I do say no will I regret it? will I feel i've missed out on making some really interesting (and, not to put too fine a point on it, valuable) friends? What;s your experience been?
