My oldest GS always called me Mommy-al, the rest is Grma

When my mom was alive, she was called the mean ol Grandma. this is a name she gave herself when my kids tried to tell her that their other grandma let them do this or that. she would say, well I'm the mean ol grandma. even when they were grown they still called her that with much affection. Even the great grandkids knew her by that. She even got packages through the mail addressed to "Mean ol Grandma. the postmen always knew who that was. Me, I'm just grandma or grandma G. I love the name grandma.
