The summer gig turned into my day job. I was an arts administrator who helped make indie flicks. At the filmmakers' encouragement, I tried shooting a couple of shorts of my own. Directing was stressful, it was not my strength. But writing the scripts and helping others with their scripts - that was a gas. Making stuff up the way I wanted to see it was the biggest kick I ever experienced.
Etiquette is about all of human social behavior. Behavior is regulated by law when etiquette breaks down or when the stakes are high - violations of life, limb, property and so on. Barring that, etiquette is a little social contract we make that we will restrain some of our more provocative impulses in return for living more or less harmoniously in a community.
