Eating lunch today on the patio of the coffeehouse, I saw the strangest thing: a yellow jacket wasp flew to the table, landed on my liverwurst, carved out a bit, rolled it into a ball, held onto it, and flew away. My partner and I were amazed. A few minutes later, the wasp returned. I let it land on the meat. It repeated the same process. We watched in awe. Then, we were done with lunch and cleaned the table.
The wasp came back as we walked away. The table was empty.
