Nowadays, the problem of not preserving family boundaries becomes more common between citizens. Well, obviously it is true and the are many causes for this issue.
To begin with, there always were and will be families with lack of conventions, as that are the main part on maintaining communication between members, family relationships become poor. Traditions are one of the main part of close-knit family. In modern society, especially among youngers family becomes something, that has no priority for special bonding or festivals. For instance, children prefer to spend their birthdays with friends, instead of sharing this special day with family members. That is to say, codes of conduct have changed and family communication go on the second layer.
However, with the well-development world, humans prefer to create career, trying to climb the career ladder, instead of creating extended families, where all relatives live under the one roof and have close relationships. In other words, today, people become more selfish, as they want to complete their own needs, forgetting about the richest thing they have-family. For example, there are numerous singers, sportsmen and artists that usually miss bondings, as they have a lot of work.
To conclude, i strongly agree that family communication becomes worse in modern society. It mostly depends of two common reasons as i said earlier. Some measured must be taken to avoid development of this issue.
