Oh yes, I am ashamed to say I have said it, in fact I have screamed it once, when I totally lost concentration when driving and almost pulled out in front of another car at a junction !
I must admit it happened a few times, only ever in the car, in horrible crazy traffic/horrible weather/lost, needing to concentrate etc, and they were bickering, fighting and crying in the back, it was the final out of control response when bribes, threats, gentle prompting to be quiet, had not worked, and the alternative to telling them to shut up was to pull over to the side of the road and run for the hills, alone.
That was when the demon mother came out, however it obviously did not traumatise them enough, because the car bickering, fighting and even hurling things at each other continued on a regular basis for a long time. thankfully car journeys now are much more pleasant and interesting (7yo and 12yo).
