When in Rome,do as the Romans do.

Every could has a silver lining.

Don't judge a book by its cover.

To kill 2 birds with one stone.

Actions speak lounder than words.

Scratch my back and I ll scratch yours.

An eye for an eye,a tooth for a tooth.

The Grass iss always greener on the other side of the fence.

The pot calling the kettle black.

Birds of a feather ,flock together.

Walls have ears.

All that glitters is not gold.
