I've never used words as have been described. Honestly, I promise that the only time was when my abusive husband unleashed a diatribe at me I said one of them, considered it and decided it was demeaning. I would most certainly never use bad language in front of my children. An 'O.... (space for brain to kick in) for goodness' sake ' was my standard.
So then these children go into school and use this language and get sent home etc. etc... education interrupted...all down to horribly bad parenting.
No, Islay, there is no, repeat 'no' excuse for using bad language before children. The first time I have really understood the divergence in our views. No excuse.
