Hot Air Balloon

A man in a hot air balloon realized he was lost. He lowered his altitude
and spotted a man in a boat in a lake below.

He shouted to him, "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 man in the boat consulted his portable GPS and replied, "You're in a
hot air balloon, approximately 30 feet above a ground elevation of 2346
feet above sea level. You are at 31 degrees, 14.97 minutes north
latitude and 100 degrees, 49.09 minutes west longitude.

The man in the balloon rolled his eyes and said, "You must be in
economic research."
"I am," replied the boatman. "How did you know?"
"Well," answered the balloonist, "everything you told me is technically
correct, but I have no idea what to do with your information, and I'm
still lost. Frankly, you've not been much help to me."

The boatman smiled and responded, "You must be a trader."
"I am a trader," replied the balloonist. "How did you know?"
"Well," said the boatman, "you don't know where you are or where you're
going. You made a promise that you have no idea how to keep, and you
expect me to solve your problem. You're in exactly the same position you
were in before we met, but somehow, now it's my fault."
