The Mooresie

This morning was garbage day on my street.
i was waiting for the bus when i noticed a grocery bag a few houses down the road. It was beige and unmarked. The opening was tied up, but from the lack of inertia in its movement, the bag looked empty.
The way it was keeping balance while being blown by a light wind, it looked like the bag was a large-cat-sized mouse, with a knot for a tail, skittering back and forth across the road.
A truck eventually came up the street towards me and narrowly missed the mouse, but the slipstream was enough to blow it upwards and make it roll and twist. The illusion of life was broken and the mouse became a bag again.
