kindness

In every situation it is always appropriate to be kind. In fact, silence can be the nicest thing you say or give to someone. Always ask these three questions before you give an opinion or speak your mind:

Is it true?
Is it necessary?
Is it kind?

If the answer to any of these questions is "no", then let the moment pass and find another time when the information can be conveyed in a positive and helpful way. Perhaps the information is simply your opinion and doesn't ever need to be conveyed.

Buddha said this much more eloquently:
"If it is not truthful and not helpful, don’t say it.
If it is truthful and not helpful, don’t say it.
If it is not truthful and helpful, don’t say it. 
If it is truthful and helpful, wait for the right time.
"
