Just crashed into a Lamborghini!

I'm always going to take the side of functional language over prescriptive grammar. My wife gets vexed when I say 'of' rather than 'have' in the context mentioned above - shock horror! I make linguistic mistakes - but if the spoken implicature isn't rendered ambiguous by the error, then I don't really give a fuck. I find it mildly irritating in written language, but again, if the message is unmuddied, then I've got plenty more bigger fish to fry in the sea or whatever, guy.

You're absolutely right of course, but once a sub, always a sub...
