I don't charge because I wasn't charged and I don't have to make a living from it. If I had to pay rent I would charge, simple as that. The best reason for not receiving money is that I don't have to be beholden to anyone to reciprocate. I don't become a hired servant.
"Look, I'm only doing me job. I have to show you how to defend yourself against fresh fruit."
For it breeds great perfection, if the practise be harder then the use. Sir Francis Bacon
