A couple of years ago, I had to leave an am dram group of which I had been a part for many years. I had to leave for a number of reasons: some were political, but I was also expecting DS1 and was very poorly. I had counted myself to have many "close" friends at the group, but only managed to maintain contact with a few. In the meantime, the friends I had managed to maintain fell out with the rest of the group and I subsequently felt that I had been even more cut off by proxy.
It's all really very childish I know. However a couple was married this week, and I feel so sad to think that once upon a time, I would have been a part of the celebrations. I bought a small gift as a token of past friendship (they came to the evening of my wedding) and best of luck for the future. Not really sure I should give it though. They've obviously moved on. Maybe I should too. :(
