Buzz… bumble… buzzzz
They make noise! As in “bumble.” They are not bumbling. When I was a kid in West Virginia I awoke and put on my jeans one morning. All the while I heard a buzzing in the room. I walked about and the sound followed me to the window and back. When I dropped my jeans a very large bumble bee flew out. I was happy enough that he did not sting me. And he was happy to be in the world again. I do so love a happy ending.
