It is not movement that destroys the machinery, but friction." Helen Hunt says there is one sin which seems to be everywhere, and by everybody is underestimated and quite too much overlooked in valuations of character.

It is the sin of fretting.

It is as common as air, as speech; so common that unless it rises above its usual monotone we do not even observe it.

Watch any ordinary coming together of people, and we see how many minutes it will be before somebody frets--that is, makes more or less complaint of something or other, which probably every one in the room, or car, or on the street corner knew before, and which most probably nobody can help.

Why say anything about it?
It is cold, it is hot, it is wet, it is dry, somebody has broken an appointment, ill-cooked a meal; stupidity or bad faith somewhere has resulted in discomfort.
