Sam had worked 30 years for the same company and now he had to retire.[19]As a sign of gratitude, the company held a dinner in his honour. "Sam," announced his boss, "it is my great honour to present this gift to you on behalf of the company." Sam walked down to the front of the table and accepted the gift with pride. It was a gold watch and on it was written "To faithful Sam for 30 years of service."[20]Sam wept. "I am at a loss for words."
    At home, Sam’s wife looked at the gold watch critically. "For this you worked 30 years? A cheap gold-plated watch?" "It’s the thought, dear," answered Sam. "The important thing is that I am not working any more." His wife held the gold watch to her ear and said, "Neither is your watch."
