Isn't it so Irish to chance your arm, get away with it, and the instant you get called on it, lead off with "Well this is an unseemly argument and we must draw a line under it now and move on".
But the moment something arises where a quick action would resolve the problem - like, say arguing about the mass grave in Tuam instead of getting on the train to Tuam with a shovel and a camera, which would have avoided months of Terry Prone-ing everyone - we waffle till we fall asleep.
