This is lifted from another forum I was once on, and demonstrates my point perfectly. 'Twas my finest pedantry point scoring hour I think.

Back to the question: No, don't get rid of grammer schools. If it ain't broke, don't fix it.
I wish we had the old system again, where if your kid gets into the local grammer then they go there, and if your kid doesn't then they go to the comp and either study academic subjects or a trade. That way the clever ones do well, and the not so clever ones at least have something they can be proud of.
I've had a mixture in terms of education: Private, grammer, CofE, bog standard london comp (moved around a lot as a chlid). Private was definitely the best, they let me do a GCSE at 10! When I got to London they didn't let me stay in my school year (I had been moved up in private school) because I wouldn't 'handle it psychologically', that sucks because they held me down with idiots and then I missed the boat on being able to get grants for uni.

Hannah, please note it was a GRAMMAR that you allegedly went to, and a fat lot of good it did you, obviously.
Me
It wasn't just that Becks, though it did add insult to injury. And I agree about the correcting thing - it's a bit rude and unnecessary, we all have different skills and sometimes it's just down to genuine typos, and God forbid anyone should want to test me on my maths! But sometimes people ask for it!
Hannah
Sorry, yes, GRAMMAR, I am quite embarrassed. I shall say it was a mere slip of the finger. Gosh people love to pick on you if you make the slightest mistake, I've seen some awful spelling on here sometimes but nobody's bothered about that!

If we're getting into correcting mistakes: I think you'll find you're 'playing devil's advocate' rather than 'paying' it. Glass houses, stones ....

Grable, my mistake of 'paying' rather than playing devil's advocate was a typo, as opposed to a spelling mistake or confusion over the wording of the phrase. In contrast, Hannah made the same spelling mistake three times in one post. I don't usually make a habit of correcting grammar, punctuation or spelling, as like Becks said, it could turn into a full time job. However, I felt Hannah was rather arrogant in her posting. She claims to have been moved up a year at school, to have taken a GCSE at ten, and attended a Grammar school herself at one point. I don't object to that, good luck to her if she was bright enough. But to refer to being educated within the appropriate academic year group for her age as 'being kept down by the idiots.' was very offensive. I would never normally seek to humiliate someone, but given that she was keen to point out her intellectual superiority I think the old saying 'people in glass houses...' applies more to her than me.
