If you got something that bothers you, and you would like to complain with your friends, colleagues, boss, partner. First, consider the following questions.
Is there anything I can do about it?
Can I think of a way to make it better?
Can I contribute to the discussion to come up with a solution?
If the answer to these questions is no, then the “something” is probably out of your reach, and you’d probably better not to complain about it in the first place.
There’s a caveat. Abuse, in any form, in any situation, is never acceptable, and you should always bring that up and seek help.
In all other cases, do act only if by doing so you are seeking support and resources in overcoming the situation. Complaining without an idea, a plan, sounds a lot like complaining for the sake of complaining. In general, people don’t like it.
