I do remember that when I was about 6 or 7 y.o. our number was 23743, and the "old lady" who lived about nine houses to the north had 34723. She was probably a very nice old gal, and I was told that she was a retired "children's book writer" but I don't think I ever saw her.

It was obvious though that she - and apparently several of her friends - had reached the CRS stage, as I was carefully taught to say - politely and slowly - "I believe the number you want is 34723." We got several calls a week when her friends transposed the numbers, for several years. She even called a few times when she wanted her caretaker to come for her.

Now if I could remember my current phone number ...
