I went to elementary school in Alabama in the 1960s. My first grade teacher was very kind but also very strict. She kept a wooden paddle on her desk as a warning against misbehavior and she used it often. One day at recess, some girls were playing and began doing cartwheels. They were wearing dresses and as they went upside down their dresses fell, showing the white panties that were underneath. This, of course, caught the attention of a friend and me and we began to watch and then tease the girls, “I saw you panties na na na na.”
