It all depends on what you want. You can trust us to stick to you through thick and thin – to the bitter end. And you can trust us to keep any secret of yours – closer than you keep it yourself. But you cannot trust us to let you face trouble alone, and go off without a word. We are your friends, Frodo. Anyway: there it is. We know most of what Gandalf has told you. We know a good deal about the Ring. We are horribly afraid – but we are coming with you; or following you like hounds.”
Merry, The Fellowship of the Ring, Book 1, “Chapter V: A Conspiracy Unmasked,” p. 104.
