A man in a hot air balloon realised he was lost. He lowered altitude and spotted a woman in a boat below. He shouted to her, "Excuse me, can you help me? I promised a friend that I would meet him an hour ago, but I don't know where I am."
The woman consulted her portable GPS and replied, "You're in a hot air balloon approximately 30 feet above a ground elevation of 2,346 feet above sea level. You are 31 degrees, 14.97 minutes north latitude and 100 degrees, 49.09 minutes west longitude."
He rolled his eyes and said, "You must be Helen Zille, the Leader of the Democratic Alliance."
"I am," replied the woman. "How did you know?"
"Well," answered the balloonist, "everything you told me is technically correct, but I have no idea what to make of your information, and I am still lost. Frankly, you have not been much help to me."
The woman smiled and responded, "You must be Jacob Zuma the President of South Africa and the African National Congress."
"I am," replied the balloonist. "But how did you know?"
"Well," said the woman, "You don't know where you are or where you're going. You have risen to where you are due to a large quantity of hot air. You have made a promise that you have no idea how to keep, and now you expect me to solve your problem. You are in exactly the same position you were in before we met, but somehow, now, it's my fault.
