They walked to the IHOP to have a celebratory lunch. Being back in Florida felt just right to her. Francis, the leader of the paramilitary wing of the AARP, threw them a salute and blew her a kiss, and even Lester's nursing junkie friend seemed to be in a good mood. When they were done, they brought take-out bags for the junkie and Francis in the shantytown. "I want to make some technology for those guys," Perry said as they sat in front of Francis's RV drinking cowboy coffee cooked over a banked wood-stove off to one side. "Room-mate-ware for homeless people." Francis uncrossed his bony ankles and scratched at his mosquito bites. "A lot of people think that we don't buy stuff, but it's not true," he said. "I shop hard for bargains, but there's lots of stuff I spend more on because of my lifestyle than I would if I had a real house and steady electricity. When I had a chest-freezer, I could bulk buy ground round for about a tenth of what I pay now when I go to the grocery store and get enough for one night's dinner. The alternative is using propane to keep the fridge going overnight, and that's not cheap, either. So I'm a kind of premium customer. Back at Boeing, we loved the people who made small orders, because we could charge them such a premium for custom work, while the big airlines wanted stuff done so cheap that half the time we lost money on the deal." Perry nodded. "There you have it -- roommate-ware for homeless people, a great and untapped market." Suzanne cocked her head and looked at him. "You're sounding awfully commerce-oriented for a pure and unsullied engineer, you know?" He ducked his head and grinned and looked about twelve years old. "It's infectious. Those little kitchen gnomes, we sold nearly a half-million of those things, not to mention all the spin-offs. That's a half-million *lives* -- a half-million *households* -- that we changed just by thinking up something cool and making it real. These RFID things of Lester's -- we'll sign a couple million customers with those. People will change everything about how they live from moment to moment because of something Lester thought up in my junkyard over there." "Well, there's thirty million of us living in what the social workers call 'marginal housing,'" Francis said, grinning wryly. He had a funny smile that Suzanne had found adorable until he explained that he had an untreated dental abscess that he couldn't afford to get fixed. "So that's a lot of difference you could make." "Yeah," Perry said. "Yeah, it sure is."
