Friends have been defined as people who know you at your worst and like you anyway, people in whose company you can be yourself. But perhaps more than anything else, friends are people who care about you for who you are, not what you can do for them. There is a kind of holiness in true friendship, because it makes sure that we are never alone when we desperately need to not be alone.
When from our better selves we have too long
Been parted by the hurrying world, and droop,
Sick of its business, of its pleasures tired,
How gracious, how benign, is Solitude.
