Bluff Called in Edinburgh Part1

Leaning on a 1920's Bentley in Edinburgh you might think I owned it. I was trying to impress a pretty Scottish lass standing close by.

Humiliation stared me in the face. Panic was creeping in.
Thinking on the hoof I blurted: "I'm taking the salute at tonight's tattoo and must rush off to don my dress uniform for the parade. "Black Watch?" she asked "I adore men in kilts and sporrans - can I come too?"
