Despite your best efforts and intentions, there's a limited reservoir to fellowship before you begin to rely solely on the vapors of nostalgia. Eventually, you move on, latch on to another group of friends. Once in a while, though, you remember something, a remark or a gesture, and it takes you back. You think how close all of you were, the laughs and commiserations, the fondness and affection and support. You recall the parties, the trips, the dinners and late, late nights. Even the arguments and small betrayals have a revisionist charm in retrospect. You're astonished and enlivened by the memories. You wonder why and how it ever stopped. You have the urge to pick up the phone, fire off an email, suggesting reunion, resumption, and you start to act, but then don't, because it would be awkward talking after such a long lag, and, really, what would be the point? Your lives are different now. Whatever was there before is gone. And it saddens you, it makes you feel old and vanquished--not only over this group that disbanded, but also over all the others before and after it, the friends you had in grade and high school, in college, in your twenties and thirties, your kinship to them (never mind to all your old lovers) ephemeral and, quite possibly, illusory to begin with.
