Blustering, short-tempered dads are a tried-and-true TV sitcom trope, but the tendency to anger quickly and easily isn’t a harmless personality quirk in real life. If you have a short temper, it can make your family tense and on edge, bracing for an outburst every time something goes wrong. Even if you stop yourself from, say, kicking the un-put-away toys that lie around the living room, and even if your anger never leads to violence or shouting, chronic grumpiness nevertheless affects your relationships, not to mention the mental health of everyone in your family. This is what to remember — and how to stay in control.
