I caught an animal today

Coworkers noticed the mouse, frozen and clinging to the wall, just above a bright red alarm bell. I stood on a chair and poked in its general direction with an umbrella. The mouse, confused and in a panic, scurried down for a bit until performing (deliberately or not) its equivalent of skydiving without a parachute. As soon as it hit the ground, it started running. A colleague helped me corner it between a filing cabinet and a basketball, and using the plastic bag I had handy, I caught it by the tail and wrapped it in the bag.
It stopped fidgeting now, and became very still in its white prison. Unsure of what to do with it, I took the stairs down to the office building's front entrance. I crossed the street and went, shivering, to the narrow patch of grass separating the byway from the main thoroughfare. It was snowing a bit, the earth was patched with white. I turned the bag inside out to find the little rodent immobile. I couldn't tell if it was in a state of paralysis brought on by shock, or just plain dead –from the fall, the exhaustion or the panic. I laid it down at the root of a tree and headed back into the office, feeling wrong.
