Back in the 1970s telephone companies charged for long distance calls. Maureen and I lived in Fort Wayne with our two little boys, Don and Jeff. Don was two years older than Jeff. One day we received our telephone bill and were shocked to see that we had been billed for over fifty one-minute calls to Akron, Ohio.
After a short parental investigation, we discovered that Don had been teaching Jeff how to make music and count on our touch-tone phone. After a brief explanation by Maureen, GTE generously waived the Akron calls.
