Why Mae Mae?

My name is Mary Susan McConnell.  When my sister was born, we knew 'Mary Susan' would be difficult to learn at first.  So my family started referring to me as Mae Mae, which of course she learned very quickly.  Today she calls me Mary Susan half the time and Mae Mae the other. Throughout the years, various friends picked up the nickname and started using it themselves.   Today, I go by Mae, Mary Susan, Mae Mae, and Hot Mama.  Just kidding. Nobody calls me Hot Mama, but I'm hoping that catches on too.
