(She wasn't so much complaining about the children swearing, she was asking the parents to stop swearing around their children, especially on and around school premises, after pupils had been caught repeating swear words that they had heard their and other parents using.

I have received complaints regarding parents swearing when bringing children to and from school.
Swearing is not permitted on school grounds and I ask all parents to think about the language you use when on school grounds. Thank you for your consideration with this matter.
Tell them to wash their mouths out with soap, and stick them on the naughty step.
