We leave Jacob for some indeterminate past or present. The porch roof bends crazily... magnets don't work, hair turns gray or curls, as magazine subscriptions expire involuntarily and disinformation creeps into the newscasts. Just another day in Chaotic Space.     I didn't really understand what was going on until the first time it seemed to happen to me, one afternoon, when I went out to the backyard, to open up my hives.
