If you've gone out drinking and carousing with someone, don't later claim you never met the guy.
Never let someone you know to be a hired assassin double as your fishing boat captain.
If you are a body guard and you "call in sick" the day there is an assassination attempt on your boss, don't show up for work again.
Dont' let yourself go soft in the head by playing comedy with a young girl.
You can act like a man, and don't turn out like some Hollywood finocchio saying, "Godfather, what can I do?"
If there is a known plot to assassinate you, don't pause on your way to the car to see some guy imitating a donkey, or to listen to your daughter whine about her love life.
Don't let someone give you a cup of tea right before bedtime.
