Everything has an end.
A sheep cannot bleat in two different places at the same time.
Do not make the dress before the child is born.
Do not mend your neighbor's fence before seeing to your own.
Even flies have ears.
Even the night has ears.
Events follow one another like the days of the week.
In the world all things are two and two.
The roaring lion kills no game.
We start as fools and become wise through experience.
