The rain had stopped before I went for a walk. My mother had returned home before I did my homework. We had met in the street before we went to the park. They had packed their things before then they started. I had switched on the TV set before I had dinner. He had returned home before the guests left. We had came to the cinema before the film began. I had read the book before I saw the play. They had lived here before they moved to another place. We had played a game of tennis before we went to my place.

You hasten to make people laugh.
Without difficulty, you can not catch a fish from the pond.
Soon you'll go - you'll hurt your foot.
The word - not a sparrow, will fly out - you will not catch it.
If you want to eat kalachi, do not sit on the stove.
Murder will out.
Further put, closer you will take.
If you give yourself the will, you'll lower your father's share.
On the mare you will not drive.
Do not chew - do not swallow.
A sieve of water can not be applied.
Without measure and bast shoes do not weave.
Byl - not a fairy tale, you can not throw out a word from it.
You can not take a throat, you do not abuse abuse.
For the unkind you will go, you will trouble yourself.
