"It's just as likely as not," said Bob, "one of these days; though there's plenty of time for that, my dear. But however and whenever we part from one another, I am sure we shall none of us forget poor Tiny Tim—shall we—or this first parting that there was among us?"

"No, never, father!" they all cried again. (4.135-138)
