If you're aware of a potential problem, you are half way to solving it. If you're worried about an adverse reaction that someone might have or an argument that they may put forward, you've probably got no reason to worry. By and large, in life, it's the element of the unexpected that proves most challenging. What you're expecting (or half expecting) you can easily cope with. And as for what has the potential to surprise you, well... remember today, it also has the potential to prove entirely and pleasingly predictable!
