It was the couple who saw us first. They were going at it like knives among the ivy. She was a blonde.

We looked at her and she looked at us. Then she pushed the bloke off her. The guy ran after her desperately trying to protect his privates from the brambles.

We did not know where to look. Good job all 12 people on the tour were adults because sometimes kids come along.

One elderly man was so incensed, he was ready to chase after them with his walking stick but I persuaded him to calm down and eat his sandwiches.
