One variation on this (mostly untrue or misleading) rule is that we don't need to worry about what other people think of what we're doing.

"What will the neighbors think?" was a realistic worry in small-town America 100 years ago. But in these times, everyone is too preoccupied trying to make it through their own day to pay much attention to others not named Kardashian. So there's no need to be self-conscious over minor spills or pratfalls.

I'm glad to know I do have friends to call when I need comfort or advice. Most people don't know me well enough to care, but I have my little community. And that's all anybody really needs.
