Summary
The families have so many problems but most of them come from 3 main categories, Husband and Wife, Siblings and parents/children.
These problems are mostly from not believing each others, not trusting them or to overcome/overdo something and try to be more superior than others. The way we prevent it is to behave and treat others equally, both mother and father, brothers and sisters. This way, the problems will be less and the family will be happy.
