I've tried warm milk before bedtime, and all I get are angry clowns at a ghetto carnival.

Why do you suppose the angel/demon/bird/parasite host/old man becomes "familiar" to the people? What is Marquez saying about humans' ability to "grow tired and bored" of a situation?

A Very Old Man with Enormous Wings

Question one asks why the "angel's" appearance is so unsettling. I remember I told you guys a story about the nightmare I had about the Easter Bunny. He was so huge he was bent over at the waist to fit inside the house, and his fur was matted with dirt and motor oil. The manner in which he "marched" from room to room in my house, all slumped over, was truly nightmarish. If you've ever played "Doom," the bunny was like the monster that chases you all over and appears instantly in doorways.
The "angel" has that same quality. He's basically toothless, with only a "a few faded hairs on his bald skull." Instead of standing regally upright, he's stooped in the yard, not saying anything. The fact that he can't communicate adds to his sinister quality. Imagine if you had died and gone to the "Pearly Gates" but when you got there, an angel was guarding the gates. Imagine, too, that when you spoke to him, he answered in a gibberish that you could not understand. Imagine exactly how "excluded" or "damned" that would make you feel. Here you are, at the gates of heaven, and you can't communicate with the angel whose job it is to let you in or keep you out. Now THAT's damned!
