A woman in hot air balloon realized she was lost, so she reduced altitude & shouted to a man below..
"Excuse me Sir, can you help me? ... I promised a friend to meet him an hour ago but I don't know where I am."
Man below replied :-
"You are in hot air balloon 30 feet above the ground. You are 41 degrees North latitude & 59 degrees West longitude."
Lady :- "You must be an Engineer !"
Man :- "How do you know ?"
Lady :- "Everything you told me is technically correct but useless & the fact is I'm still lost."
Engineer :- "You must be in Top Management."
Lady :- "Ya. How do you know ?"
Engineer :- "You don't know where you are or where you're going. You have no technical knowledge. You made a promise which you've no idea how to keep & you expect people beneath you to solve your problems!"
