A Rolled Paper Tube

I noticed a sturdy brown cardboard tube resting horizontally against the baseboard near the entryway. I stood quietly for a moment, letting my eyes adjust to the soft indoor shade. Then, taking two careful steps forward, I gave the round edge a gentle press with my bill. It rolled forward with a low, hollow hum across the floorboards, revealing a tiny white button that had been hidden underneath. I paused and watched it settle against the doorframe, perfectly quiet once more.
