Why would you say "she"? Is "her" somehow offensive now? Or have they forgotten objects of prepositions are, well, objects?

Seriously, "spoke to she"? I've never heard that. And I dread to think of the blood-boiling it would cause in me if I were to hear it... As gcv says below, "Mary and I" as the object of the verb is annoyingly common, even among well-educated people. No, it's not language evolution; it's wrong!

edit: ah, you're gcv :)

"ask" as a noun is fine (even outside of finance). I've never seen or heard "spoke to she" and Google doesn't seem to turn up anything.

I hear it occasionally. I hear its equally-appalling equivalent all the time: "Please join Mary and I in welcoming John to our team."

Of course, prescriptive grammar is for the birds, anyway.

That's surely just an over-reaction to people being told "and I" in response to a sentence like "Mary and me would like to welcome John to the team". You can't win.

As a kid, you get 'Me and Mary' as the subject corrected to 'Mary and I' for reasons of both grammar and politeness. Some people don't understand or remember the compound reason and just use 'and I' everywhere.
