He hadn't needed to, of course. We both knew the way things work. Corps and corporators don't give gifts; they make investments. Barnard had invested in me, and we both understood that some time down the road he'd come looking for a return on that investment. Over the intervening four years, he'd never mentioned the matter; hell, I'd never had anything to do with Yamatetsu during that time, and that was just the way I liked it. But again, he hadn't needed to mention it, or remind me. Megacorporations the world over have integrated a lot of ideas from the old Japanese world-view. When someone is in your debt, it's his responsibility to remember the fact, not yours to remind him.
