Families in the past are bigger than now, they consist of two or three generations wich live together in the same home. I mean, Nuclear Family was composed of many children ,parents ,cousins ,aunts ...

From joint Families , a place where the children learned several values such as repect, honesty, sincere , even the way to eat, or the way to communication and relatioships between all members of familiar group even yo could listen please and thanks almost everything.

The grandparents used to be a good position and they were  respected by their grandsons .
