Is it just me?
I get why people who don't want people parking in front of garage doors start their sign/notice with POLITE NOTICE. Presumably it's in the hope that some people will mistakenly think it says POLICE NOTICE. Personally I don't think it works, and that it makes the person putting up the notice a bit of a dork, but I can live with it.
I have just received 4 text messages from my daughter's primary school, which start "polite reminder". What's that all about? Am I to assume that unless they tell us the message is intended to be polite then we should take offence? Or that all messages not so headed are intended to be impolite?
Or do they intend that we think that the police have become interested in the current amount of unpaid dinner money, or the summer uniform arrangements?
