Yes, I am vaguely aware that they are Okies, and my mother's family being from Texas, we would take pains to differentiate ourselves from those Okies. I am not sure what all is behind that, but anyway we have no place for the clueless "Grapes of Wrath" book in our personal library, notwithstanding its Nobel laureates. Sometimes people forget that fiction is only fictional, not a story resembling any actual person dead or living.
