Don’t know a whole lot about my stepmother’s mother, but my dad’s mom....my grandmother certainly didn’t do a lot of dancing. A Pentecostal preacher’s wife didn’t dance, go to movies, didn’t read much of anything except the Bible etc. My dad on the other hand, did a lot of dancing and especially liked the Texas Bop and the Jitterbug.
I can't picture either one of my grandmother's doing anything more than a genteel waltz but my parents were champion jitterbuggers. Boy, could they dance! Even in their late 50's, they could cut some moves.
