The ladybug tapped on the front door and waited. No answer, which was to be expected. Ladybugs being rather small, their knock is difficult to discern. The best way to hear a ladybug knocking at your door is to know when they are expected, open the door, and watch them crawl up to the threshold, lift one appendage, and knock. Even though the door is already open, Ladybug, being nearsighted, and truth be told, not very bright, will make the knocking motion on the air where the door should be. The problem, at least from the ladybug’s perspective, is to wear soft shoes, or no shoes at all. The reason being, when you open the door to leave, if there were to be a ladybug knocking, you’ll crunch the poor creature beneath your shoe.
