What is the biggest difference between having a father and not having a father?

That's a world of difference. A family with a father will have better economic conditions and a better family environment, and then feel better at home.

A family supported by men will feel warmer and warmer.

Generally speaking, children without fathers are often laughed at by other children.

Those children are not so heartless.

It's just that some children think that what others don't have will have some childish happiness, but this state will hurt some childless fathers.
