That might be the way that economists describe shortages, but it is not the way that normal people describe shortages. Personally, my definition of a shortage is "There is not enough of X, and it would be a very good thing to increase X". Using my bread example, if bread cost 100$ a loaf, and people were literally starving to death because they couldn't buy bread or other food, then there IS a shortage of food. It does not matter if "supply is equaling demand", because it is a very bad thing for food to cost 100$ a meal.
