"This does not mean we are to be perpetually solemn. We must play. But our merriment must be of that kind (and it is, in fact, the merriest kind) which exists between people who have, from the outset, taken each other seriously--no flippancy, no superiority, no presumption. And our charity must be a real and costly love, with deep feelings for the sins in spite of which we love the sinner--no mere tolerance, or indulgence which parodies love as flippancy parodies merriment."
--C. S. Lewis, The Weight of Glory (Been thinking of this for the last several weeks. Anyway, I'd just as soon quote the whole essay. Definitely worth reading.)
