Life happens. Things happen. People act out of character (where they are already acting into their character.)
In an ideal world you would want to sit with yourself and figure out a solution. Or go for a walk. Or leave things as they are for a bit. Meditate. Or perhaps a combination of all.
But when you interact with people, it is important to remember that you show up as a composed human being. Someone who does not allow any mood swing to swing their behaviour too.
Our bad mood must have no bearing on the goodness we ought to offer into the world.
Deal with your crisis. But don’t download it to others.
