Dear Writers of Fanfiction

I, Gandalf the White, kindly wish to inform you that I do not know who or what "The Avengers" are, nor do I know what they are avenging, or what they have avenged.

Furthermore, I'm afraid I fail to understand the usefulness of a "Hairy Potter" in war. However I do know a most excellent potter in the Shire, if you must know.

Your grasp of the reality troubles me greatly.
