A man in a hot air balloon realised he was lost. He reduced altitude and
spotted a woman below. He descended a bit more and shouted, "Excuse me, can
you help me? I promised a friend I would meet him an hour ago, but I don't
know where I am." The woman below replied, "You're in a hot air balloon
hovering approximately 30 feet above the ground. You're between 40 and 41
degrees north latitude and between 59 and 60 degrees west longitude."
"You must be a software engineer," said the balloonist.
"I am," replied the woman, "How did you know?"
"Well," answered the balloonist, "everything you told me is, technically
correct, but I've no idea what to make of your information, and the fact is
I'm still lost. Frankly, you've not been much help at all. If anything,
you've delayed my trip."
