A person who can be silly without embarrassment has escaped one unnecessary prison.

The fear of looking foolish governs an enormous amount of adult behaviour, and most of it is unnecessary. Being able to be silly without a wince means one of the main levers people have over you no longer works, and a whole category of enjoyment becomes available again.

Do one undignified thing in front of people who matter to you. Sing badly, dance badly, play the game properly. The relief is immediate and it makes the next one easier, which is roughly how the prison gets dismantled.
