The married business executive had to make a trip to Palm Beach alone for his corporation.

After a few days he was enjoying himself so much that he decided to stay another week as part of his vacation.

His friend was quick to wire back: Your wife and I arriving tomorrow 11.30 a.m. How long have you known about us?
