How to Have a Happy Family? Part 1

All humans have their own expectations. An expectation is "predicting future according to present conditions & past experiences." In a family life, members' expectations are approximately closer to each other, comparing with those outside this family group because they have relevant "past experiences" and/or relevant "present conditions." Of course, "past experiences" plays an important part since it is related to memories and, of course, memories are related to feelings and emotions, psychologically.
Whenever we make use of the term "expectation", we should not forget about another term, "altruism" if we are going to reduce the possibility of potential clashes between members of a vital social group called "family".
But what is the meaning of altruism? It is defined as "ignoring your own happiness in favor of the happiness of others." Of course, in a cohesive family, happiness of other members must make us happy, too. So, in a family, an altruist ignores one happiness to achieve another happiness. Certainly this happiness is sweeter. We should remember that altruism is "a mutual reaction" so the definition above can be rewritten this way:
"Altruism is a mutual reaction in which one ignores one's own happiness in favor of the happiness of others."
Then a family life can be bolstered if our expectations are managed considering the existence of a phenomenon called altruism.
Of course, these two terms in other groups of society need their own definitions. The blog just discussed these terms in a family life.
