This just hit me today, how I am free to be myself here, in a way that doesn't sell in the USA.
By nature, in "public," I am not only cheerful, friendly, respectful, courteous, gracious, and appreciative, but enthusiastically so. I really enjoy, selfishly, radiating positive energy, selflessly. In any context with other people in it, it's how I want to be. It's my nature.
But that doesn't fly in America.
