wife
How I explained REST to my wife...
"Some days the Powerbook gets more attention than the wife and so she snoops over my shoulder and starts asking a bunch of questions about whatever is on the screen. She doesn't really care, this is just the cue to shift my attention over to her. I usually do just that and say something like, Oh, this is some interesting stuff but nothing you would care about.
But on this day I decided that I would play along a bit and see how far I could take her into my world before she ran away screaming in terror."
