A Surprise Visitor

Polly came back from her early morning stake out with boggly eyes and a bushy tail. She then came and sat inside the rear window of the caravan, trembling. What had given her such a shock? Another wasp sting? No. Something she had never seen before... a horse! On the top field. It was a bit of a sorry looking horse, with a back so curved, that it looked like a saddle had been implanted under her skin. I recognised her swishing tail. Through the trees near the entrance to our drive, you can always see the rear end of a horse, with a tail swishing. I thought it was a false horse bottom which acted as a warning signal to the landowners that someone was at the perimeter of their property. No, I actually did allow that thought to cross my mind.
I know how to say 'Your horse is in my field' in French, and Kevin doesn't, so guess who went to tell the neighbour, the neighbour we haven't yet met? Kevin... because he is a social animal. He soon came back with a long-haired rock star in baggy pants. He was French, but spoke good English. The horse is his sister's. She was not in. He phoned her. Could the horse stay until the evening? Yes. The rock star thought the horse would stay on the top field all day, as the grass is so green. The horse managed half an hour before it got bored and left. Kevin followed it, and it took him back to its own field. Horse adventure over.
