Ah - well with the school one, I admit it is partly when they call me Mrs Notmyname, and so (think I said this somewhere else) I sort of want to challenge both of those erroneous assumptions at once. And why would I not challenge them by giving the correct title as well as the correct surname?
But Pendeen, would you expect me to just be called Mrs even though I'm not? And should I give the incorrect answer ('actually it's Miss') rather than the correct one?
This is making me think though.... there are a few people in job #2 who call me Mrs or Miss depending on their whim (it's a school, so titles obv used). I don't correct for various reasons.
But, but but.... dp was once in a situation where over a number of months a colleague thought he had been to university A when he'd actually been to university B. Dp wasn't ever sure whether colleague was joking because the universities are 'rivals' and so he didn't correct although started to wonder whether colleague actually was being teasy or just had it wrong.
Then there was some situation where DP got asked by someone else and had to tell them, in front of said colleague, who was mortified at not having had his mistake pointed out earlier ('why didn't you say, I feel a right idiot now and you must have thought I was one all along' kind of thing.
So what if you suck up Miss or Mrs or whatever it is you're not, and then people think later, why on earth didn't she say? Did she think I would be chippy about it or something?
Given that you don't know what people are going to think is wankery, then, I have decided that it is best to stick with the truth, and let people think what they want.
(sorry for length there!)
