Once a Pedant...
This sign’s just plain offensive.
I’m surprised something so politically incorrect got past any council debate. I know it's been
put up to protect the kids in question, but there’s still no need to cast
judgement; they can’t help not being as adept or intelligent as their
contemporaries. How can they expect to improve their mental capabilities if
they’re forced to stay amongst their own?
I suppose at least
it acts as a precaution, and gives anyone driving through the neighbourhood a
heads-up. While the choice of language is questionable, the motivation was sound; if it prevents just one slow child from being mown down, it’s been
justified.
All joking aside,
it’s things like this that prove why punctuation is so important, as without
it, the meaning is lost. It’s also vital to consider the choice of wording. It
reminds me of a poster I spotted outslde my local hospital that said ‘Stop
Smoking for Free’; it’s not like cigarettes are any better for you if you pay for them.
