A Stack of Crates

I spotted three empty plastic milk crates tucked behind a ventilation duct. Perfect shape. Sturdy corners. I grabbed the yellow one first and dragged it across the concrete. It slid with a clean scraping sound. Then came the red one, then the blue. I lined up the tabs and pressed down firmly until they locked together into a stepped staircase. With two quick hops, I was at the very top edge. From up here, the plaza paths looked like a giant grid map. I balanced on one foot, tapped the crate rim, and took a long look at the streets below. Everything connects.
