Your post was great. I just see it so often on this and other boards.
I just don't want learners thinking "Oh, I'm in the US, so simple past is all I ever need to know."
(Yours really didn't say anything like that, I know. It's the compounding influence of seeing it that may lead people astray.)
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
