A man is flying a hot air balloon and realizes he is lost. He reduces his height and spots a man 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 about 30 feet above a field."
"You must work in Information Technology," says the balloonist.
"I do", replies the man. "How did you know?"
"Well, everything you told me is technically correct, but is of no use to me."
The man below says, "you must work in sales."
"I do", replies the balloonist, "but how did you know?"
"Well, 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 in before we met, but now, it's my fault."
