Swatted a spider a few weeks ago. It flew through the air and landed on my back. Saw something on the floor a few days ago, picked it up to throw away, and it was a live spider. I figure spiders are just trying to live with us on this planet too and, so far, no bites. Saw "The Dark Side of Spiders", on the National Geo Channel today. Learned that they've been evolving for 400 million years. Now, that's a very long time.
