Most people look forward to Friday because for many of us it's the end of the working week. It's the day we get paid, if the firm is still solvent, and as we hurry to catch the Five Thirty we know the train is taking us home to a weekend of rest and relaxation. Unfortunately, Friday is also the day that can finish your beautiful weekend before it even starts. It's the day your wife suddenly develops a heavy cold and has to retire to bed leaving you with a straight 48 hours of cooking, scrubbing, cleaning and baby-sitting. It's the day when a week of glorious sunshine comes to a dead halt and the monsoon season sets in. It's also the day when the boss gives you that folder to glance through at home if you have a minute. Which means you are going to be working like the clappers until well after midnight on Sunday. Even in the Navy, Friday can be the day that heralds a distinctly dodgy weekend as Captain Povey is about to find out.
