Blustering, short-tempered men were once a tried-and-true TV sitcom trope, but the tendency to anger quickly and easily isn’t some 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 toys left strewn around the living room out of your way, and even if your anger never leads to violence or shouting, chronic crankiness still affects your relationships — not to mention the mental health of everyone in your family.
