A woman I know gave me a build-it-yourself bird-feeder kit for Christmas, so I built it, and hung it from the eve of my roof high enough to keep the birds save from my cat. But the birds scratch the seed out of the feeder, then fly down to the deck and eat the seed. They know there's a cat, but still they go down to pick at the seed. When you think about it, people are often like this, too.
