Be careful what you wish for - you may get it.

If we say what we like, we may hear what we don't like.

Hell is not as bad as the road that leads to it.

Tell secrets and you become their servant.

If you can't swim, don't jump in at the deep end.

Watch out for the fellow that lets you do all the talking.

Don't test the depth of the water with both feet.

Talk too much and you will soon say something you didn't intend to.

Be careful when an enemy speaks kindly.

An ally has to be watched just as much as an enemy.

There is no rose without a thorn.
