I am a teacher. In the last few weeks I have been told that some children in my school are allergic to their school uniform, suffer with extreme cold and so need to wear coats in class, have to keep jewellery on because it is sentimental, should be allowed to use staffroom facilities to microwave their own lunch....don't even start me on phones.
DH works with much older DCs - adults, essentially - and has put up with a whole range of shite from parents recently too, making excuses for why their (fully grown) offspring should take precedence over the needs of every one else.
Of the last 20 tales we have been told between us, I reckon 1 is true, 1 is half true and the rest are absolute bollocks.
Either front up and be honest about trying to bend the rules, or just fucking accept it.
