Fudd, I used to have a neighbor who was always playing practical jokes on us. I never got a chance to get even...UNTIL...one day when my neighbor and his family went out for the day and I discovered their little dog was wandering around outside and heading for the street.
I took him home, found their front door unlocked, put him inside and closed the door after him. A little later he was out wandering around again. Obviously, that pup knew how to paw the door open.
That time I brought him to my house and put a bright red and white kerchief on him. Then I took him home and made SURE the door was locked.
My neighbor arrived home to a house securely locked and his previously unadorned dog sporting a kerchief.
It took the neighbor about 24 hours to figure out how it was done and who had the most reason to "get even" with him. His response was to cross the street to my house and smilingly hand me the biggest gin and tonic I had ever seen.
That's a great story!
