Night Patrol Warning

I checked the dark passage behind the TV cabinet before settling in for the night. People leave things where they don't belong, and that leads to trouble. Back there, behind the thick tangled cables, I discovered an empty cardboard shoe box standing half-ajar like an unauthorized entry. I used my right wrist tool to wedge an abandoned plastic bread clip firmly into the gap between the box lid and the rim, locking it tight. Then I dragged a heavy yellow plastic highlighter right in front to mark the perimeter. Anyone thinking of poking around behind this cabinet will see the boundary clearly.
