I used to have a teacher who taught class barefoot. Miss Palladine, who then became Mrs Dauz. She was my history and homeroom teacher in 5th, 6th, and 7th grades.
She taught class barefoot several times. She also used to have this one tan pair of shoes, that hurt her feet, and she would sit down on the desk next to mine, and teach class either barefoot, or in tan stockings. One time, she noticed me looking at her feet, and mouthed to me "Those shoes hurt my feet".
Her husband was a lucky SOB. She was beautiful. I heard he unfortunately passed away a few years ago, but they were married for a long time.
