"A wizard is never late! He arrives precisely when he mean to!"

Ты shall not pass

Bilbo: "Good Morning." Gandalf: "What do Ты mean?" "Do Ты wish me a good morning, или mean that it is a good morning whether I want it или not; или that Ты feel good this morning; или that it is a morning to be good on?" Bilbo: All of them at once."
