I'm losing the appetite for strangers. Once I would have focused on the excitement, the hazard; now it's the mess, the bother. Getting your clothes off gracefully, always such an impossibility; thinking up what to say afterwards, without setting the echoes going in your head. Worse, the encounter with another set of particularities: the toenails, the ear-holes, the nosehairs. Perhaps at this age we return to the prudishness we had as children.
