You can manage your anger by recognising the times of the day when you are most irritable and then avoiding emotional discussions at these times.
When you finally confront the person who has made you angry, try to listen to their side of the story. Always think before you speak and avoid saying things that you will regret later. Also, avoid accusing the other person (You did/said this …) and instead, focus on your own feelings and possible solutions to the problem.
