Do not make premature judgments

I love this line from the concluding pages of the chapter, The Fast Train to Canton, which appears halfway through the book, Riding the Iron Rooster, by Paul Theroux.

It made me think that you never really know anyone until you have traveled 10,000 miles in a train with them. I had sized them up in London, but they were all better and worse than they had seemed then, and now they were beyond criticism because they had proved themselves to be human.
