Penny and I were in a local park and came across a discarded lunch, consisting of two pieces of bread and a fried egg. I didn't notice the fried egg. I thought it was three pieces of relatively low-interest dry bread. (Of course, subsequent events proved Penny did notice the succulent egg.)
We approached the food and practised "leave it' with great success. Penny turned away and received her treat - rabbit meat treats.
We did it again.
And I, flushed with success, decided to do it one more time, and to film it. Bad idea.
