With books

there is no forced sociability. If we pass the evening with those friends—books—it’s because we really want to. When we leave them, we do so with regret and, when we have left them, there are none of those thoughts that spoil friendship: ‘What did they think of us?’—‘Did we make a mistake and say something tactless?’—‘Did they like us?’—nor is there the anxiety of being forgotten because of displacement by someone else.
