This invoice speaks quite well on its own. Please spend a moment reviewing it.

Businesses do things like this more often than you might think. Long-term commerce, as it happens, engages human virtues. One-shot trades (like the proverbial used-car sale) don’t, but ongoing commerce with customers buying over and over (as at a grocery) cultivates humane and reasonable behavior.

What we’re seeing here is a company operator who had virtues cultivated inside him or her, and is acting accordingly.

So, before venturing back into the mundane, please spend a few moments with this invoice, and with this comment from a historian named John Maxcy Zane:

Trade makes for honesty, fair dealing, mutual comprehension, sanity and soundness, toleration of others, peace among men, aggregations of capital, division of labor, the ease and comfort and grace of life, the leisure for study, and the amelioration of customs and manners that produces so large a part of civilization.
