There has been some excitement here at Lakeland Court recently owing to the inexplicable appearance of some big brown crop circles in the nature-strip at the end of our cul-de-sac. My astute neighbours Wendy and Marita were a little sceptical…

“Sally, did you happen to do some mowing a few days ago,” Wendy asked.

The penny dropped.

“Oh the crop circles?” I asked.”I thought I would do you a good turn,” I added, “but your grass was thicker than ours.”

They nodded and laughed with relief because they had not been visited by aliens.
