Why do we love our children?😶😶😶

When a child is born, he receives the enormous amount of love from parents and all the relatives. Why is it so important to give to your child as much love as possible. It is so, because after he or she starts to communicate with socium, it will start to steal the love portions from him or her day to day.
Elder people are so disengaged and haters, as they do not have any love left. Remember, all children in the age 3-5 are all friends. Graduating from high school you have maximum 4 pals. Final year in college there is most often only one friend.
While life proceeds, you meet a lot of people, whom you do not care about and communicate only as you have to get something. The emptiness feeling as becoming bigger, as you spend you love budget, with no top up.
Humans are doomed, as they do not have any humanity left.
Good luck!
