My grandmother would never kill a beetle. My grandfather used to always tell her that he would live his next life as a beetle.
He builds his castle and defends it with a will that belies his size. He’s fierce and strong, but flip him over and he finds his legs flailing wildly in the air. Set him on his feet though and he’ll keep on going and going, working and building.
Maybe this is why he gets himself flipped over. Maybe pedalling in the air is a form of escapism. Keeping on going and being strong can become a chore. Have you ever annoyed a beetle? Angry little bugs, they can be!
