If a friend of mine gave a feast, and did not invite me to it, I should not mind a bit. but if a friend of mine had a sorrow and refused to allow me to share it, I should feel it most bitterly. If he shut the doors of the house of mourning against me, I would move back again and again and beg to be admitted so that I might share in what I was entitled to share. If he thought me unworthy, unfit to weep with him, I should feel it as the most poignant humiliation.
Friendship exists outside our modern economy of scarcity... It's not about apportioning vanishing resources of time and energy. Friendship is a blessed relic of the ancient economy of the gift, and the time freely given to people dear to you actually creates magical abundance.
A friend who is far away is sometimes much nearer than one who is at hand. Is not the mountain far more awe-inspiring and more clearly visible to one passing through the valley than to those who inhabit the mountain?
