Here's another example. I was on the train in December and looking forward to a pretty quiet 3-hour train ride, had my laptop with me, was going to get a bunch of work done.
At the first stop 45 minutes from my city, a HUGE group of kids got on...with Santa Claus! They all entered the train and started singing Christmas carols. Santa was jingling his bells and the other kids who were already on the train were incredibly excited. This lasted for about 30 minutes until the next stop, when Santa and the kids got off at the next town. Mrs. Claus and another group of kids were waiting for them.
I have no idea what it was all about. I lost those 30 minutes of work during the Christmas carols and general pandemonium, but goodness those kids were excited and had so much fun. I could have complained. Instead I joined in and sang carols, and it's a great memory. And I don't even really like kids.
Sometimes it's worth it just to go with the flow in an unusual situation and realize that the power of everyone else having a special moment outweighs your own preferences. (Medical conditions are different, of course.)
