就是說:對壹個難題來說，太容易的解決方法是不可靠的。
e.g
A說: i'm bankrupt, and if i can't pay the rent this month, i'll be thrown onto the street! but if i go and rob the bank, all my problems will be solved!
b說: that's wrong , remember:For every problem,there is always a solution,which is so quick, so appealing, and so wrong.
robbing a bank to pay for the rent is like that.
