On another note

Have you ever looked at your friends?
What a silly question, I know. I mean, we look at our friends everyday (in fact, one of them needs a shave, I think), but, of course, I'm talking about a different kind of "looking". The metaphorical kind that goes much deeper than the skin, than the ordinary.
Yesterday I noticed something about my friends, I noticed that of a fairly large group of us we want to become teachers, doctors, psychologists, humanitarians, and various other things that involve helping others, guiding others. Now, I realize that it's quite common for people, especially the young and impressionable types of people found in universities to want to help others. However, I find it excessively interesting that somehow, through what could largely be random chance, we have found and surrounded ourselves with such types of people. None of us want to be historians, lawyers (I don't think), librarians, bankers, accountants, etc. We aren't interested in putting a coldness between us and others. We aren't in this education business for the sole reason of making money. All of us can agree that money is nice, money is necessary, but ultimately the majority of us are interested in "humanity". And it doesn't matter what our faculty is.
We all have that interest invested in others. How does this happen? How do people come together, friends mostly because we live conveniently in the same building, in the same hallway, and end up with this deep-rooted likeness to each other. Of all of the people who I first met, first hung out with, I now live with three, and am friends with all. The first thing we asked was not, "what is your purpose in life", though, oddly enough, this was our first drunken philosophical conversation, approximately a week and a half after meeting. I am aware that people befriend based on convenience and similarity, but I find it remarkable that we found each other. Was it chance? Was it instant realization that basically we must all have such similar backgrounds and goals? Are all university students now just in it for others?
Who knows. One day I might actually study these questions, but as for now I remain overtired at eleven pm, and procrastinating from my studies that will turn me into a humanitarian. I hope.
