Coming up with the odd one liner is no substitute for being of good cheer. The odd one-liner may cause a good guffaw, but that laugh passes quickly and, in the larger scheme of things, does not make up for an abiding lack of cheerfulness.
Remarking that someone’s redeeming qualities are becoming more and more elusive may be a clever way of understating the obvious, but it’s no substitute for a day’s work.
That’s why they call it work.
Be of good cheer.
