Once you have notice what causes your anger, especially if it has been caused by another person, see if you can express it, at first to yourself, in terms of what you need. Please don’t blame the other person, but respect their position and put it in a way which is likely to get their understanding and cooperation.
Try and use “I” statements. For example: When I come home I need a few minutes to unwind. I find I get angry when I have to respond to demands right away. I know you have been busy too and we have a lot to get through of an evening, but would you mind giving me a second before asking to help out with the chores? I would appreciate it.”
Remember not to engage the other person until you feel you can do so in a way that doesn’t threaten them or disrespect their position. This could take up to an hour after you first got angry.
If you can’t find such a position, you may still wish to make a statement about your anger. However, when you are at the height of your angry feelings it is unlikely that the issue will be resolved, especially if the other person isn’t able to hear your perspective and receives them as criticisms. This will depend on the nature of your relationship and each persons personality.
To summarise, try and think of what has made you angry. Try and phrase this in terms that account for the other persons perspective of the situation also. Try and put it in a way that you think will maximise the other persons chances of hearing you without feeling attacked themselves. Then calmly state your case. If the other person escalates, don’t follow.
