Learn how to present yourself in the place of another person. Sometimes people take out the evil in any innocent others due to strong irritation, fatigue, depression, anxiety, etc. Try to be milder in these situations, do not need to maintain aggressive partner, talk to him gently, quietly, and after everything returns to normal, forget what happened and do not make mention of him ever. Remember that some people become very irritable during a serious illness, and can even tell a offensive words, but to take it seriously not worth it. Learn to forgive friends.
Go concessions when necessary. Both you and your family members are not perfect, everyone can have its drawbacks, which have to learn to live with. Listen to the other party, do not ignore his words and try to understand them correctly. For example, a pregnant wife to the husband may complain of feeling unwell, and he did not want to listen to, interrupts and asks whether you want to buy her a pill. Women need no medication and care, attention, affection, but my husband does not want to understand it, and as a result there is cause for scandal.
