A man walked into a store and spoke abruptly, "I need four apples, three eggs, a broom, a dustpan and well ... I suppose we need don't need any flour."
After a pause to regard the new man, the shopkeeper replied, "The storm last night turned my world upside down. Much of my stock has been ruined." He paused a moment to look around. "We have no apples ... only one unbroken egg, one remaining broom, three dustpans and four bags of flour, though you don't need any of those."
The point of this story is plain to hear, if you have eyes to see. Taste and touch won't help you now, no matter how you plead. Tell me now and feel free to explore, what should the man have said at the door?
