Horsing

Sir John was in love with Lady Mary. Every day he was riding his white horse under her window hoping to attract her attention but in vain. One day he decided to paint his horse green thinking:
“When I pass under Lady Mary's window she will ask me why my horse is green an I will answer: because I love you!”

The next day Sir John was passing under Lady Mary's window on his green horse.

“I love you Sir John!” - cried out Lady Mary

“And I have a green horse!” - replied Sir John.
