I'm loving this thread! that's probably an expression I should not use, isn't it. I am though, i am, loving it that is.
I dislike the use of "of" instead of 'have'. I loathe people starting a sentence with "I'm sorry, but", not only because as Newist says, if you have to apologise in advance, don't say it. I find it's used to excuse being deliberately offensive. Just as some people say 'I call a spade a spade', when they mean they actually enjoy causing offence.
I confess to missing hearing the phrase 'totes amaze balls'. It was one of my youngest's giddy expressions of joy - and she's now 6 months into travelling. I may ask her to say it when she skypes, though I fear she is more sophisticated as a result of her travels….. plus, it was always tongue in cheek. Sad eh.
