A friend sent a video of people dancing. There were adults and children, swinging their hips and high stepping it to a great beat. It was a response to a challenge called Jerusalema and after watching his I went on to view a bunch more. I shimmied in my chair, and felt the rhythm pulsing, but truth be told I think the people moving had a better time than I did.
My daughters are involved in improv, and I have gone to a couple of shows with them in the past. It was funny, and I laughed, but not as much as the people on stage.
"Mom, the thing about improv is, the actors always enjoy it more than the audience."
There are no reliable instruments for calibrating delight. How can anyone compare the amount, as if it were snow and all you need is a ruler? Back when our family sang in the shepherds' choir, people thanked us for adding to their experience of Christmas. Yet those words were icing on an already decadent cake.
I suppose it is the same with many things. Observing a gesture of kindness can pull me out of a slump, but being the one who is high stepping into it is even better.
