The lie often goes further than the truth.
The person with least knowledge talks most.
The pitcher goes often to the well and gets broken at last.
The pot calling the kettle black.
The proof of the pudding is in the eating.
The quill is mightier than the sword.
The wish was father to the thought.
To be caught between a rock and a hard place.
To put the cart before the horse.
Trage immer einen grünen Zweig im Herzen, es wird sich ein Singvogel darauf niederlassen.
