Now, if you have a green balloon, they might think you were only part of the tree, and not notice you, and if you have a blue balloon, they might think you were only part of the sky, and not notice you, and the question is: Which is most likely?”
“Wouldn’t they notice you underneath the balloon?” you asked.
“They might or they might not,” said Winnie-the-Pooh. “You never can tell with bees.” He thought for a moment and said: “I shall try to look like a small black cloud. That will deceive them.”
“Then you had better have the blue balloon,” you said; and so it was decided.
