It’s okay to be happy even if the people around us are miserable.
Our well-being does not depend on anyone else being any particular way.
Imposing suffering on ourselves so that we can suffer alongside others will only drag us down to a level that impedes our growth and the growth of those steeped in misery. To believe that we can only be happy when those around us are happy is dysfunctional.
If someone is having a bad day, let them. This may sound mean or cruel to some. While we can offer our sympathies and support, we needn’t insist that they be other than they are just so we can feel better. If they ask for our opinion, we owe them our honesty without judgment.
They will work it out. Or, maybe they won’t. But the choice is ultimately up to them, and the most loving thing we can do is to allow them the freedom to make those choices, even if their decisions do not please us.
