The man below says: "Yes, you're in a hot air balloon, hovering 30 feet above this field."
"You must be an Warrant Officer", says the balloonist.
"I am" replies the man. "How did you know."
"Well" says the balloonist, "everything you have told me is technically correct, but it's not useful to me."
The man below says "you must be an Officer".
"I am" 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."
