The higher up, the greater the fall.
The leopard cannot change its spots.
The more noble, the more humble.
The more wit, the less courage.
The outsider sees the most of the game.
The pen is mightier than the sword.
The pot calls the kettle black.
There are spots in the sun.
There are two sides to every question.
There is a skeleton in the cupboard.
There is kindness to be found everywhere.
There is no general rule without some exception.
