That’s a cogent observation. But you also have admit that this ‘bonding’ is also behind a lot of bad music, such as (getting behind my lead shield) the Dreadful Grape, the stadium rock, or ___________ (your favorite to hate), and also behind nostalgia for those good times with people who shouldn’t even have been your friends.
I just remember my high school days and the endless arguments we would get into over who was the better guitar player, drummer, etc.
But where would we be without all those mistakes we may or may not have made? They ARE our memories. It’s what made the given experience what it was and left it’s mark on us. For better or worse.
