I've worked in schools as well.
Oh, my goodness, let's go and see Mrs J in Medical = fuck, fuck, FUCK, nobody's finger should be pointing in that direction/that is a LOT of blood coming from their nose.
Oh, crumbs, thank you for reminding me = fuck, fuck, FUCK, I'm in the shit if I don't get that sorted RIGHT NOW.
Oh, botheration = BALLS, BALLS, FUCKING HAIRY BOLLOCKING BALLS
Really? = What the FUCK did you just say to me?
Righty-ho = Why the FUCK do I do this job?
Well, really [sigh] = who the actual FUCK do you think you are talking to?
Oh, fiddlesticks [turns around and goes back down three flights of stairs, crosses entire site in the pissing rain, takes evasive manoeuvres through entire complement of KS4 dawdling between lessons with a skill comparable to a ninja whilst secretly habouring a wish to possess rollerskates, a sharpened hockey stick and a starring role in a real life remake of Rollerball] = FUCK'S SAKE
Oh, I'm terribly sorry, I didn't quite catch that? = are you feeling lucky, punk?
Well, quite. However, shall we pop along to Inclusion/the Deputy Head and have a little chat there? = I'd like to tell you to get the fuck out but, sadly, I'm not allowed to. So I'm taking you where you can be an aggressive little shit to somebody else and hopefully not have to deal with you again for a couple of days.
Mrs Bloggs? Ugh, appalling woman, simply ghastly and her husband is a beastly individual = Fucking Nazi bitch, if I ever have to endure a call from her about how we are demeaning the civilising influence of the Empire and promoting violent gang she means black culture at the expense of the silent majority again, I swear I'll do her and her fucking Hitler Youth husband a serious fucking mischief with a broken fucking lacrosse stick next Sports Day.
Well, it is rather irksome = I am currently resisting the urge to rip off his head and scream FUCK OFF down the gaping hole for this most recent example of pedantry. But I rather like eating and prefer not sleeping on the street, so I will go back into the 4000 row and 87 column spreadsheet/database and retype everything in B, F, N and AA as a text field rather than a value because he prefers to see the time and date separated by full stops and NOT THE WAY IT'S SUPPOSED TO BE SO THAT YOU CAN FILTER AND SORT THE FUCKING THING AND YOU WILL BE COMPLAINING THAT YOU CAN'T DO BY FRIDAY AFTERNOON YOU FUCKWITTED MORON.
I found it [a meeting/encounter/conversation] all a little - uh - disquieting. = FUCK ME, that guy's creepy as fuck, all my fucking spidey senses were screaming at me the run the FUCK away and if my skin could crawl anymore than it did, I think it would have crawled off me and hidden under the table by itself when he fucking smiled bared his teeth at me.
Born diplomat, me.
