Fetish? Proper grammar, please.

So ridiculous, but true (for me).

Total turnoffs?

• People who say "would of"/"could of"/"should of"
• People who don't know "their/there/they're"
• People who don't know "it's/its"
• People who don't know "your/you're/yore"
• People who can't spell
• People who use incorrect grammar
• AND OMG WHERE DID THIS ONE EVEN COME FROM: People who say "WAH-LA" or some such bastardization of "voilà"

True confession: One of the reasons I've never dated a "native," an "organic," or FOB guy: I don't think I could fight the urge to correct every little linguistic mistake...

EEK.  Am I a horrible, anal person?
