When I was a little kid I went to a summer camp one year and we had a kid in my cabin who was the type who brought a lot of grief on himself. The kind of kid who walks up to a group of other kids cutting up telling the yo mama jokes they all know from their respective schools, hears a "yo mama so fat" joke, and starts gets so stressed out about his mom not being fat that the other kids just can't help piling on more and more until the poor kid is nearly in tears and has to get talked down by a counselor. He just couldn't ever come to realize that lashing out at every little thing that upset him was just gonna lead to loads more grief than letting things go.
Anyway I can't remember why exactly, but one day this kid got so wound up that he ran out of the cabin and climbed a tree in the woods nearby. Some other kids went after him to try and get him to come back and eventually his cabin counselors and the ones in the next cabin were all gathered around this tree tying to talk the kid down. He wasn't having any of it. He said he was done with camp and wasn't doing any more activities and nothing could make him come down from the tree. Eventually, the head of the camp notices the kids and counselors from two cabins are all gathered around a tree on on the treeline of the woods, comes over to see what's going on, sees the kid in the tree, and asks what's going on. Kid tells him he's had enough and he's done with camp. So the head of camp just says "Well, I hate to hear that. Stay up there as long as you need, the rest of us are gonna go on down to the lake and go swimming." Dude tells us all to go on about our day and leave the kid be. About 10 minutes after we get to the lake the kid came running down from the cabin with his trunks on to join in with the rest of us.
I never met that kid again after that summer, but I like to think that he learned a valuable lesson from the head of camp that day about the power of letting things go instead of getting worked up over all the little things people do that may get to us. Took me a few years to realize just how wise his actions were.
