You can forgive people who do not follow you through a philosophical disquisition; but to find your wife laughing when you had tears in your eyes, or staring when you were in a fit of laughter, would go some way towards a dissolution of the marriage.
Your joy is your sorrow unmasked. And the same well from which your laughter rises was oftentimes filled with your tears. And how else can it be? The deeper that sorrow carves into your being, the more joy you can contain. Is not the cup that holds your wine the very cup that was burned in the potter's oven? And is not the lute that soothes your spirit, the very wood that was hollowed with knives?
What I find interesting is how close you can run the laughter along the seam of seriousness, and occasionally cross it, so that half the house genuinely doesn't know whether to laugh or cry. Custard pie humour is fairly universal, but at the other end, which I'm more interested in, there's the humour that hovers on the darkness, that walks in the shadow of something else, not always that obvious.
Humour is but the faint terrestrial echo of the hideous laughter of the blind mad gods that squat leeringly and sardonically in caverns beyond the Milky Way. It is a hollow thing, sweet on the outside, but filled with the pathos of fruitless aspiration.
Those who grieve frequently find themselves alone. Missed is the laughter of children, the commotion of teenagers, and the tender, loving concern of a departed companion. The clock ticks more loudly, time passes more slowly, and four walls can indeed a prison make. I extol those who, with loving care and compassionate concern, feed the hungry, clothe the naked, and house the homeless. He who notes the sparrow's fall will not be unmindful of such service.
The old man laughed loud and joyously, shook up the details of his anatomy from head to foot, and ended by saying that such a laugh was money in a man's pocket, because it cut down the doctor's bills like everything.
Haste thee, Nymph, and bring with thee Jest, and youthful Jollity, Quips, and Cranks, and wanton Wiles, Nods, and Becks, and wreathed Smiles, Such as hang on Hebe's cheek, And love to live in dimple sleek; Sport that wrinkled Care derides, And Laughter holding both his sides.
