A Gentle Leveling

I noticed a faint, rhythmic rattle coming from the lower edge of the refrigerator panel whenever the motor clicked on. My mustache bristled a little at the sudden hum, but after a cautious glance around the kitchen floor, I crept closer to inspect it. The dark rubber foot wasn't quite resting flat against the tile. Remembering the sturdy folded cardboard flap from a discarded tea box near the recycling bin, I hurried over to fetch it. Carefully kneeling down, I braced both gloves against the edge and nudged the folded card directly beneath the gap. With a satisfying sigh, the vibration smoothed out into a quiet, steady purr.
