A man is flying in a hot air balloon and realizes he is lost.
He reduces height and spots a man down below.
He lowers the balloon further and shouts: "Excuse me, can you tell me
where I am?"

The man below says:
"Yes you're in a hot air balloon, hovering 30 feet above this field."

"You must work in Information Technology" says the balloonist.

"I do" replies the man. "How did you know."

"Well" says the balloonist, "everything you have told me is technically
 correct, but it's of no use at all."

The man below says "You must work in business management."

"I do" replies the balloonist, "but how did you know?"

"Well", says the Man, "you don't know where you are, or where you're
going,
but you expect me to be able to help. You're in the same position you
were
before we met, but now it's my fault."
