I’m a stickler for grammar and speech as well. It’s classist, I know. But even as a little kid, I picked up on terminology that other kids used that in retrospect reflected poverty (mee-maw, pop-pop, commode (for toilet), yeller (instead of yellow)). At the time, I couldn’t explain why I disliked it, but I considered it deficient. I’ve come a long way in dismissing those views by myself, but I can’t not notice.
