"Single-serving friends"

It is late.  Today (yesterday, more specifically) has been nothing in a productive sense.  I did a trivial amount of homework, but shortly after came home from the library to eat lunch, and I killed my time fidgeting with the TV.  Well, the hour and a half of today really hasn't seen me accomplish that much either, except to write these few pieces.  To be honest, yesterday was actually counterproductive, as I was essentially fired from my research assistant-ship by the graduate student I was supposed to be working under.  All of her points are valid, especially how I should check my email and be in touch more than once every few weeks.  It does nothing to lessen the pain.  I admit that I truly looked forward to working on this project.  Not to say that the pain is unbearable, but it most certainly isn't fun, either.
My social network at school is incredibly small, and I feel bad turning to the same select two or three to help me resolve my problems every time I turn the corner.  It makes me feel like such a burden to them.  I never feel that I can make up to them all the times that they have helped me out.  It frustrates me both that I do not think I can be as good to them as they are to me and that I have so few to turn to down here.  I do not know how to address that issue.
I am also slowly becoming irritated that my job with the school will be (hopefully) coming to an end within the year as I finish my studies.  I am not looking forward to having to find a new job, and honestly have not begun the responsible task of starting to look for one.

I find myself with the occasional benefit of running into random people and getting to have their acquaintance.  I believe The Narrator describe them to Tyler Durden as "single-serving friends."  I met a young lass at a club meeting who caught my fancy.  As I walked one of the pathways on campus one day, I strolled past another young lady on a bench.  After having the thought that I would probably never see her again and having nothing to lose, I doubled back to ask her opinion on where to take the young lass from the club on a date.  She answered, and it took no more than two minutes.  Surprising me, she returned tit-for-tat and asked me a question regarding her boyfriend four hours away whom she feared was cheating on her with his ex.  We ended up spending an hour and a half discussing the situation.  When she grew tired, I walked her to her dorm and gave her my number in case she wanted my help again.  I have yet to hear back from her.  A "single-serving friend."  I find that I enjoy these encounters, perhaps because I see myself as hopefully helping someone or because of their ephemeral nature.  Unique, but lovely.
