The best way that a man could test his readiness to encounter the common variety of mankind would be to climb down a chimney into any house at random, and get on as well as possible with the people inside. And that is essentially what each one of us did on the day that he was born.
I've gotten to that point where I'm so used to being sweaty, wearing pants, and sitting like a guy in boots. When I'm dressed up and people are touching me up and doing the whole thing, I'm less comfortable with that.
