Balancing Act

We drove to Eyemouth this afternoon and booked in to the pub. This evening, we had a lovely meal, then sat wth some of the locals and had some chat and a laugh.
There was a pile of nails on the bar, and I asked what they were for... you had to balance 14 nails on the head of a nail. The local said if I put a pound in the Charity box, he would show me how it was done... clever!
