Dear sir!
It is a matter of opinion that the people here will give a chance to vote on time.
Of course, the whole world is on selfishness, we can not even remove it because we are also a part of this system.
We study it with us that we will get good knowledge which will benefit in future life.
We are commenting on your blog, in turn, hope that you will also comment. Maybe you can help upvote too, it is also a kind of selfishness.
If there is no selfishness then it is the mother's affection, the service that has been done for the children throughout the ages, and in return only hopes that the child becomes good by writing, becoming a successful person in life, asking nothing for himself.
thank you so much
