Last week, when your boss asked you for your view on a matter, you said you had none. But inside you were brimming with opinions. Now he’s decided to go with your co-worker’s idea, and you wished you had told him yours.

Yesterday, your neighbor vented her frustration to you about her teenage son staying out late at nights. You ran into her son that same night and scolded him, revealing what his mother told you. Now she’s pissed at you for intervening, and you wish you had stayed silent.

It can be tough to know when to speak. Self-awareness, perceptiveness and empathy are the keys to making the right decision.

Stay Silent When:

You have nothing to say. Sometimes, people speak just because there’s silence. This induces mindless chatter. If you’re talking solely because it’s quiet, you really have nothing to say. Don’t assume something is wrong because someone isn’t talking, as they may simply not have anything to say. Speak deliberately; this is the key to attaining honesty and focus.

You need time to solidify your reaction. In emotionally-charged situations, such as debates or arguments with a spouse or friend, there’s always the risk of you responding in a hurtful or aggressive manner. To gain perspective on an issue, you might need to step back and observe. This allows you to listen to your intuition and logically decipher what’s really going on.

It’s better left unsaid. Avoid revealing irrelevant thoughts and feelings. For example, there’s no need to tell your uncle that you think his wife is unattractive and he could do better. This rule also applies when someone entrusts you with private information. If you reveal what someone has told you in confidence, they’ll have a hard time trusting you again.

You don’t have a receptive listener. There’s no use talking if the other person isn’t listening to you, because the message you’re trying to convey will not be heard.

Speak When:

You want to let your feelings known. To keep the peace, some people bottle up emotions that should be expressed. For example, if your spouse made a tactless comment about your cooking, bring it to their attention instead of stewing silently in resentment. Doing otherwise can cause your pent-up feelings to transform into a sudden burst of rage when you least expect them to.
