A few years ago my sons used to help me with the collecting. Number 2 son was talking to a custy on her doorstep, when he noticed a woman on the opposite side of the road waving at him. Not wanting to appear rude, he waved back, then he turned to the custy and said: "I haven't the faintest idea who that was." "I'm not surprised," she said, "she was waving at ME"
