“Frodo was now safe in the Last Homely House east of the Sea. That house was, as Bilbo had long ago reported, `a perfect house, whether you like food or sleep, or story-telling or singing, or just sitting and thinking best, or a pleasant mixture of them all’. Merely to be there was a cure for weariness, fear, and sadness.”
– J.R.R. Tolkien, The Lord of the Rings, Book II, Ch.1, ‘Many Meetings’
