But to hell with philosophical questions. Not halfway around the temple, our government-approved guide was doing the nudge-nudge wink-wink. I don’t know if it was because he thought we had begun to drool, or if it was just the way he usually operated. But he was steering us—though I recall that wife and son went off by themselves—only to the erotica, explaining in a steadily hoarser whisper what he was about to show me, breaking into English for the most titillating parts. "Here lesbian", and "there two men, one woman", and "that is dog, heh heh"—these phrases, I remember hearing.
