My Granny, Mama's mom, had a sister who lived in Detroit. She'd come down every 10 yrs. or so for a visit. She came when I was about 11 or 12, and she taught my sister and me, and our girl cousins how to play Canasta. She called it Clean and Dirty Canasta. She cussed like a sailor, and my saintly Granny was always fussing at her for talking like that around us. We thought it was so funny!
