Our DS came home from school aged seven, and told me that his class teacher had made him stand on his chair for five minutes for being cheeky.
I would have given him 'down the banks' for being naughty, but he wasn't usually a cheeky child.
So, I asked why, it transpired that the teacher had said 'haitch' and he'd put his hand up, when she asked what he wanted, he'd told her that his mum said it was 'aitch'. So, she decided that it was appropriate to punish him for being correct!
Admittedly it probably could have been considered cheeky, but if she'd used 'proper' English he'd have had no reason to question it!
I went to school to see Mrs G. the following afternoon. She took offence, called the headmaster in to the room, presumably thinking that he was going to side with her, and had to back down when he told her that I was right, my DS was right, and she really needed to make sure that she was teaching her class correct pronunciation and grammar!
To her credit she didn't 'take it out' of my DS after this event, (which is just as well) but later that term I was checking through his English workbook, and when he had described feeding a 'squirrel' she had crossed the word out and corrected it to 'squirell'....cue angry mum making yet another visit to the school
Apparently that time was a 'slip up' because she was 'very tired when doing the marking'!
Hmmmm, maybe tired, or maybe just a bit thick
My pet hate (apart from haitch) is the Americanism of 'reach out', they don't speak to someone, they 'reach out' to them.....hate it, hate it, hate it!
