There are reasons why I avoid large scale alumni gatherings. In fact, I think a gathering of 5 is already too much of a crowd.
These outings and gatherings used to be fun when I just graduated from high school. We were kids then, and our only job was to study hard enough to get into college. High school was still a recent memory, and we tried our best to preserve that, before everyone's paths diverged.
Then these got less and less frequent as the months go by. Many forces draw us in different directions --- our courses of study, our time spent with our special other, our jobs, etc.. Besides the obligatory "what are working as?", we are quite lost for words when we do meet up.
And I knew that would happen. I've been deliberating whether to attend my middle school graduating class reunion. The attendance numbered over a hundred, which was pretty respectable for a cohort size of over 300 students. Here was a chance to meet many long-lost friends and establish lost connections! Besides, some of my teachers would be attending, and I really wanted to see them.
But such events are both overwhelming and unsatisfying. Conversation invariably stops when one has run dry of the "what's your job?" line. The fact is that most of us do not wish to discuss our jobs and its frustrations. We are forced to because there is no better conversation starters.
Group dynamics also tend to devolve back to those days when we were still 16 year-olds. In a big group, we still tend to cluster around people we used to cluster around in school, never mind that we haven't spoken for a long time. The geeks are still geeks and the sportsmen still hang around sportsmen. We have moved on in leaps, yet so little seem to have changed when we are back in each other's company. That may not be a comforting thought if one wasn't a well-adjusted kid in school.
So I opted to give the event a miss. However, I made sure I didn't miss the teachers I wanted to meet because of my decision. Of course, there are friends I wanted to keep in touch with, but I just didn't think the occasion fits that purpose. By striving to meet as many "long-lost" friends as possible in that one session, we sacrifice the depth of our interaction with them. Worse still, the brief meeting may prevent potential communication in future because we have "had our fill" at the gathering.
I believe that friends who want to keep in touch are already doing so. Hence a massive gathering that gets everyone together does little to rekindle past friendships. I prefer to see it as a business gathering.
If I seem stand-offish, it's only because I prefer a deeper level of contact with the friends I really cherish. It is much more satisfying when one meets another to share their lives over a drink or a meal, without the time pressure of having to "move on to the next friend" or "catch up" with as many friends as possible.
