A man was flying in a hot-air balloon. After flying for a while he realised he was lost. He reduced height and spotted a man on ground.
The flying man lowered the balloon farther and shouted, "Excuse me! Can you tell me where I am?"
The man below said: "Yes, you are in a hot-air balloon, hovering 30 feet above this field."
"You must be an engineer," replied the balloonist.
"I am," replied the man. "How did you know?"
"Well," said the balloonist, "Everything you have told me is technically correct, but it's no use to anyone."
The man below then replied, "You must be in management."
"I am," replied the balloonist in surprise. "But how did you know?"
"Well," said the man, "You do not know where you are or where you are going, but you expect me to be able to help. You are in the same position you were before we met, but now it is my fault."
