So I was thinking about the wave. If you’ve ever been to the Fenway in Boston, you know just what I’m talking about.
One person stands up and throws their arms in the air. And a few people around them understand the game and join that person. And before you know it, a group of people in the area are standing up, throwing their arms in the air, then sitting. And it begins again. and again. At some point the announcement box sees it happening and throws some music in. And soon enough, it forms a wave of arms rising and setting, that goes around the stadium.
I think what happens is just one person is feeling happy, and shares it. And before you know it, there is a whole stadium full of people drinking up the sunshine and doing the wave.
