I took an early morning weekday trip to the beach. Amazingly it’s almost completely empty, yay! So I set up my towel and bring out the inflatables. I inflate my Nivea beach ball by mouth, then play with it a little. (Some construction noise in the background- and also some military planes flew overhead just as I finished inflating, routine practice or something, I think). Then I deflate the ball squeezing it under my arms and hands.
