Y.T.'s mom works in Fedland. She has parked her little car in her own little numbered slot, for which the Feds require her to pay about ten percent of her salary (if she doesn't like it she can take a taxi or walk) and walked up several levels of a blindingly lit reinforced-concrete helix in which most of the spaces—the good spaces closer to the surface—are reserved for people other than her, but empty. She always walks up the center of the ramp, between the rows of parked cars, so that the EBGOC boys won't think she's lurking, loitering, skulking, malingering, or smoking.
