In my opinion, the perfect family is a very big rarity. the family is a part of society, if there were really perfect families, then it would be possible to create an ideal society, and this is just a utopia. look around, there are no perfect families - according to statistics, 80% of marriages take place on the sidelines, where you do not look - quarrels, marital treason, divorces i think this is all because people do not think well when they decide to marry or marry somebody other reasons that were close to love and were not about to lie - for example, by calculation, from coercion, etc marriage is perhaps the most important decision in our lives and to take it with him with all responsibility, before thinking well all . for by creating a family, a person now responds not only for himself, but also for his relatives, and sometimes people are not ready for this, and then the families collapse the main thing is that relations based on great love, trust and mutual respect. consequently, from all of the foregoing (although in this my post i myself will sometimes i will do such a generalization - ideal families-this is a great rarity, i would like, of course, to be more, i personally, in my future, i will try to create exactly this.
