Jonas’s family life is going to be different from your family life because his father and mother are appointed by a committee, as is his sister, and none of them are biologically related.
Although I do not know anything about your family, I am pretty sure that they were not appointed by a committee of Elders. In Jonas’s world, the community lives by the principle of Sameness. This means that everything is tightly controlled, and rules are extremely strict. One of these rules is that all family units are created for the sole purpose of raising children. There is no love. No one gets married and has a child the old fashioned way. The adults all take drugs to prevent urges that might lead to children, which they call Stirrings.
Instead, children are created by some genetic engineering process that is not clearly described or defined. We do know that babies are born to Birthmothers, raised by Nurturers in the Nurturing Centers until they reach the community age of one, and then appointed to a family that has applied for them. Family units are made of one man and one woman, formed by the committee of elders based on their capability for the sole purpose of raising children. Once the children are gone from the home, the family unit disbands and the members have basically no relationship with one another. Jonas explains this.
"As long as they're still working and contributing to the community, they'll go and live with the other Childless Adults. And they won't be part of my life anymore. … And after that, when the time comes, they'll go to the House of the Old" … (Ch. 16)
On the other hand, there are some ways that Jonas’s relationship with his parents is very similar to yours. He does still have a mother and a father. They do provide him with guidance when he has a problem, discipline him when he needs it, and celebrate his victories. They care about him, even though they do not love him. They do not have love in their world. It’s not one of their concepts. In their own way, they are parents. They treat him more in the way a teacher or foster parent would. Loving him would be inappropriate. They do raise him, in their house, from the time he is a baby until the time he leaves home.
