She was so grateful and smiley when she accepted the gift box and was unwrapping it ... until she looked in the box.
For about five priceless seconds I watched her face slowly change to rage as she realized what it was and why I was giving it to her, and screamed at me as I hustled away, with me smiling.
Lessons:
(1) A creative and appropriate response to a disrespectful trespass brings awareness and subsequent responsible behavior.
(2) Later on, this lady treated me with respect and cordiality. (She even gave me a good reference in obtaining my CDW license application.)
(3) For over 25 years, no dog deposit ever showed up on my lawn. Neighborhood dog-walkers still tend to give my property a wide berth.
(4) Not long after, the neighbors voted me as president of the village association (102 properties). In my time all complaints of animal difficulties were dealt with quickly and effectively.
