It is the spectators, the people who are outside, looking at the tragedy, from whose ranks the skeptics come; it is not those who are actually in the arena and who know suffering from the inside.

The difference between "trained OK" and "trained perfectly" doesn't really matter all that much to me. I once did a film with Lassie.
