Arriving home after a social but exhausting tennis match, I threw my bags down and raced for the refrigerator. Three glasses of cold water later, I could finally take note of my surroundings. The house appeared totally empty. Helen, my wife, had taken our 18-year-old daughter Lisa away for a mother-daughter 'bonding' weekend. This gave me the perfect opportunity to catch up with some old buddies around town over the next two days.
