I love to read Robert Louis Stevenson for pure entertainment. His insight into people just tickles me and he is always busy looking into the quirks and differences in people. Here he is talking about a good friend while they are on an ocean liner trip.

"If he had one taste more strongly than another, it was to study character. Many an hour have we two walked upon the deck dissecting our neighbors in a spirit that was too purely scientific to be called unkind; whenever a quaint or human trait slipped out in conversation; you might have seen Jones and me exchanging glances; and we could hardly go to bed in comfort till we had exchanged notes and discussed the day's experience. We were then like a couple of anglers comparing a day's kill. But the fish we angled for were of a metaphysical species, and we angled as often as not in one another's baskets. Once, in the midst of a serious talk, each found there was a scrutinizing eye upon himself; I own I paused in embarrassment at this double detection; but Jones, with a better civility, broke into a peal of unaffected laughter, and declared, what was the truth, that there was a pair of us indeed."
