Here's a little difference I've noticed about Floridians and Northerners: Up North, when we want to indicate that we'll return somebody's call, we say, "I'll get back to you" or "I told him I'd get back to him later." Down here, it's almost invariably, "I'll get back WITH you." Or, if your boss is instructing you to liaise with someone in another office, she'll say: "I told Jill you'd get WITH her this afternoon."
Where I come from, that would mean you were going to make sexy time with Jill this afternoon. Not so in the South! It still sounds weird to me. Even John says, "If she doesn't get back with you..." ...and I have to take a moment to remember what it means.
