I went back to spraying water on the lawn. A minute later, I saw the duck flying around again and this time it cruised lower, over the hood of my car, and landed on the sidewalk. Our lawn is rather small: a square about ten feet on each side. I was standing on one side of it. The duck waddled up to the center, clearly watching the spray of cool water.
So I spent some time watering a duck. She (I think it was a female) seemed to be having fun, poking around looking for snails amid the hose spray. She wasn't quite sure I was safe and would start to waddle away a few feet each time I had to take a step and shift position.
After a bit, the lawn --if not the duck-- was thoroughly watered, so I put the hose down and went to turn it off at the faucet. The duck went over to the hose and drank a few beakfulls of cool water. Then, after a friendly flip of the tail, she was off again.
Just an enjoyable inconsequential tidbit from my day.
