Wiggling can be an anecdote to being too serious/adult
Wiggling is an activity that most adults consider childish, and even ridiculous. Funny thing is that most adults can’t wiggle. So that tells me that, its not that its ridiculous, it’s that adults are hiding the fact that they can no longer (or believe they can no longer) do this thing, behind the oh-so-adult-behavior of judging. When you wiggle your body, its almost impossible to be angry, worried, or self-centered.
Wiggle for a minute and see what changes, from the inside out. You might be surprised.
