First of all, is the person displaying anger towards you? If so, you will have to decide if you want to live with this at all. However, if the person is frustrated by different issues in his/her life and is displaying anger in a non-focused way, then you may, in a friendly way, ask the person why they are angry and suggest some remedial measures, like counseling or meditation. Sometimes even a change in diet can do the trick. This may sound a little strange, but look, if a person is consuming a lot of meat there are problems according to Ayurvedic Medicine. You see, when the animal is killed, its' body is flooded with adrenalin, "the fight or flight" hormone. so going vegetarian, may have a profound effect on curbing anger. Use of illegal steroids is another suspect. What exactly are the issues? If there are really huge issues, then they may need professional help. However, if there are issues that are relatively remedial from a practical point of view, then perhaps you together can work out a solution. Again, it depends on the magnitude. Now, when you use the term "anger issues", it gives the connotation that there are emotional problems that are causing friction in the home. That is the "gist" of your question. So, I believe, that if there are not any "quick fixes", then this person may have some psychiatric issues. Some people, for example, have a tendency to be very controlling and obssessive about the details of the environment.: cleanliness, neatness,order, etc. Not necessarily rational, either. If you are being abused or denigrated, then you will need to examine why you "love" this person. This is one of the most difficult tasks that an abused person has to exercise. Unless limits are set and abuse is not tolerated, the angry person may even escalate their anger and harm a family member.
