Maybe naieve, but I have been trying to protect my son from the 'F' word and was proud to have never yet sworn in front of him.
But he just caught me posting here and read out the three imortal words "Go Fuck Yourself" when he saw it on the screen.
One of the dangers of working from home, I guess. Happy to report that he has not get witnessed any DP or similar. Guess it's just a question of not if but when...
