I recently got a new automatic dialer for my telephone. It worked by programming in a 3 number code to indicate who you wanted to call. To make things easy to remember I decided to use three letter codes to represent someone and then convert those codes to the matching numbers on the touch tone dial. For example for my brother I used "BRO" which became 276, and to call my sister - "SIS" became 747. Then I went to program "MOM"..... It explained a lot!
