Corridor Scouting

The entrance boundary was secure, so I slipped under the gap beneath the main door to scout exterior territory. Outside lay a concrete corridor with numbered doors stretching ahead. Direct observation revealed a glossy promotional leaflet jammed crookedly into the metal mail slot of the door opposite. Gross geometric infraction. I marched across the polished floor, scaled the narrow wooden baseboard, and reached upward with both hands. With a firm downward tug, I extracted the flyer from the slot. Now rolled flat under my boots, it provides an exact rectangular baseline along the wall seam. Perimeter extended.
