Weekend Reflection . Dawn encroaches on the turf so recently claimed by darkness, bringing soft blues, hints of spun-sugar pink, layers of blue-gray clouds that will meander through before allowing the sun full reign. Most of the city still sleeps. Street lamps are still lit and bounce their light off the placid waters of the canal. Grand old buildings admire their reflection another day. A few watercraft chug along, bringing supplies. The vaporettos chuff into the Rialto stops, largely empty. The narrow passageways and piazzas belong to carriers of cameras and tripods for a few minutes more, before shopkeepers appear with buckets of water and brooms to make ready for business.
