Riddle

Why are wrens like boll weevils? Because they're lookin' for a home. And every year at this time they try to nest in our medium-size rural mailbox if it's left open even a tiny crack. How can they make themselves so small? They love to work with large, soft, and brown leaves frozen on the Turk's cap stem when the first really cold weather struck. Sometimes they throw in a bit of ball moss. Maybe they even somehow pry open the door. We continue to see monarch butterflies on the lantana flowers; and there are also clouds of honeybees, which are also attracted to every flower now open, including allium. We've seen no slugs; we keep seeing the same tree lizard; we heard happy toads this morning.
