You shouldn't speak ill of a man behind his back.

It is your constant efforts that count most in the end.

The amount of time someone is willing to spend on something may communicate how important it is to him.

If you say "I was tricked," well that's certainly so but there's no mistaking that you were the one who signed up on a "sweet deal".

It is the place where there is no person in question, and you shouldn't say abuse.
