Thanks for your encouragement all!!! And yes I do adore Zorro :-). Carrie, your suggestion interested me. But can you just clarify this point:
"Get them to say hi to you and without any eye contact with Zorro offer him a treat."
Do you mean that I shouldnt maintain eye contact with Zorro, or for Zorro not to look at the "accidental" stranger?
By the way I have noticed that when I talk to strangers in the street he quietens down.
