You'd be in a pretty fair old mess without it though, unless you fancy trying to feed yourself by stuffing a spoonful of cereal into your ear works.   Sorry, just my warpted sensed of humour coming to the fore.

you mean like some of the children of some of the posters on here, who,  through no fault of their own, have little or no intelligence and yes, I guess some of them have even tried to stuff a spoonful of cereal in their ears and probably worse. Those of us with children like that also have to maintain a sense of humour, so we know what you mean...
