Two soldiers, masquerading as trees, pass me casually on the street. Aware of the possibility that they're armed, I avert my eyes, questioning their peculiar disguise only to myself. I walk on only to come upon two trees attired as soldiers. I assume that the soldiers and trees have made an even exchange, and, aware of the possibility that the trees, as well as the soldiers could be armed, walk directly toward my home.

Arriving there just after dark 1 see that the draw-bridge has been raised. I compare my situation to that of a piece of luncheon meat destined for a sandwich, only to find that the bread it was supposed to occupy is already accounted for.
