"Roundabout"

We have a fancy new traffic circle - it's actually very efficient and after suffering with construction for 4 months, was glad to see it completed.
Yesterday, a flag man was directing traffic while they painted lines. I pulled up, stopped for his sign, smiled and waved.
Eventually he allowed us to start moving again. Just as I got to exit road, remembered we had Rx's to pick up so there I was again, smiling and waving at him. The look on his face was precious.
I read his mind to pass the time, "Weird old bat, can't make up her mind."
"Can, too!!!" I yelled as I drove away.
