A hot-air balloonist realises he is lost so he reduces height to ask directions from a man on the ground.
"Excuse me" he shouts, "Can you please tell me where I am?"
"Of course" says the man below, "You're in a hot-air balloon, hovering about 30 feet above the ground."
"Thank you" says the balloonist, "I guess you must work in Information Technology" .
"Yes I do" replies the man below, "But how did you know that?"
"Well" says the balloonist, "Everything you've told me is absolutely correct - but it's completely useless!"
The man below is very miffed.
"And I guess you must be a business manager" he says.
"I am," replies the balloonist, "How did you know that?"
"Well", says the man below, "You arrived having no idea where you are, or where you're going, and you expect me to be willing and able to help. I've provided the information you asked for and you're still in the same position as before we met. But now you're convinced it's MY fault."
