C.S. Lewis on Friends.

"... the higher the common ground of the Friendship is, the more necessary the remembrance [of our shortcomings]. In an explicitly religious Friendship, above all, to forget [these] would be fatal.
For then it will seem to us that we - we four or five - have chosen one another, the insight of each finding the intrinsic beauty of the rest, like to like, a voluntary nobility; that we have ascended above the rest of mankind by our native powers. The other loves do not invite the same illusion. Affection obviously requires kinship or at least proximities which never depended on our own choice. And as for Eros, half the love songs and half the love poems in the world will tell you that the Beloved is your fate or destiny, no more your choice than a thunderbolt, for 'it is not in our power to love or hate'. Cupid's archery, genes - anything but ourselves. But in Friendship, being free of all that, we think we have chosen our peers. In reality, a few years' difference in the dates of our births, a few more miles between certain houses, the choice of one university instead of another, posting to different regiments, the accident of a topic being raised or not raised at a first meeting - any of these chances might have kept us apart. But, for a Christian, there are, strictly speaking, no chances. A secret Master of the Ceremonies has been at work. Christ, who said to the disciples 'Ye have not chosen me, but I have chosen you,' can truly say to every group of Christian friends 'You have not chosen one another, but I have chosen you for one another.' The Friendship is not a reward for our discrimination and good taste in finding one another out. It is the instrument by which God reveals to each the beauties of all the others. They are no greater than the beauties of a thousand other men; by Friendship God opens our eyes to them. They are, like all beauties, derived from Him, and then, in a good Friendship, increased by Him through the Frienship itself, so that it is His instrument for creating as well as for revealing, At this feast it is He who has spread the board and it is he who has chosen the guests. It is He, we may dare hope, who sometimes does, and always should , prseide. Let us not reckon without our Host.
Not that we must always partake of it solemnly. 'God who made good laughter' forbid. It is one of the difficult and delightful subtleties of life that we must deeply acknowledge certain things to be serous and yet retain the power and will to treat them often as lightly as a game.... For the moment I will only quote Dunbar's beautifully balanced advice:

"Man, please thy Maker, and be merry,
And give not for this world a cherry." "
