Mr. Air Conditioner, please let Shin, Mikan-chan and Mei-Shun appreciate your 25-year job. You have worked even if bats live or washed within, left never vacuumed on filters until recently. The latter 2 therefore understand why sudden teardrops fell from you last night, watering living room floor: burst into them at breaking point. Potty pads and handkerchiefs are ready for you.
