A man is flying in a hot air balloon and realizes that he is lost. He reduces altitude and spots a man on the ground below. He lowers his balloon further and shouts, "Excuse me, can you help me please? I promised my friend I would meet her half an hour ago but I don't know where I am."
The man below says, "Yes. You are in a hot air balloon, floating approximately 15 metres above the ground. Your latitude is between 40 and 42 degrees north, and your longitude is between 58 and 60 degrees west."
"You must be an engineer," shouts the balloonist.
"I am," replies the man. "How did you know?"
"Well," says the balloonist, "Everything you have told me is technically correct but I have no idea what to make of your information, and the fact is I am still lost."
The man below says, "You must be a manager".
"I am," replies the balloonist, "But how did you know?"
"Well," says the man, "You don't know where you are nor where you are going. You have made a promise, which you have no idea how to keep, and you expect me to solve your problem. The fact is you are in exactly the same position as you were in before we met but now it is somehow my fault."
