'Don't slag teachers off.' In Ull??? In the 21st Century? Are you serious? I currently have various young blood-relatives still living in Ull, whose future, unfortunately, depends upon YOU and your peers. I'm distressed to say I'm not even slightly confident for their future there, and I genuinely hope I can find some way to help them escape to reality. Education is a wonderful thing and, believe me, people like you are not on the 'plus' side of this highly nonlinear equation.
And don't even think about thanking me for pointing out your error; just keep making the same error, forever. Then, one day, you may get on to the Hull City Council. Alongside Garragher. Aaaaawesome.
And don't EVER try to make jokes about the Blitz -- that's waaay beyond bad manners, sonny. I'm sure that many grown-up posters on here lost family members -- fathers, brothers, sons, uncles, granddads, etc. -- during that dreadful time.
You've got a lot of growing up to do, before you should even think about trying to present yourself as a grown-up, kiddo. Now get back to correcting your pupils' spelling errors, if, of course, you can ... IF you agree that spelling and grammar are actually important in the grown-up world.
