"It's like this," he said. "When you go after honey with a balloon,
the great thing is not to let the bees know you're coming. 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 under the balloon?" Christopher Robin asked.
"They might or they might not," said Winnie the Pooh. "You never can
tell with bees."
