Without the modicum of relief of being able to suggest, for example, that I had a modest proposal for solving hunger and overpopulation problems, I would not be able to understand that life is as valuable as it is, and that class war is a concept that affects the poor and the rich unequally.
They decided to play with each other instead of treat everything with rigid, formal, unbendable strictness.
And being able to be comfortable and play with the one you love? Dude. That's seriously amazing.
