I see

I was sad because I lost my grandfather's kindness to me. The irrepressible sadness is because I have lost the only loved one who was kind to me forever. The point is that he's good to me, so I'm just a pity. It's not that there is nothing incomprehensible about the great creatures of human beings.

I'm just being selfish.

This is explained in biology.
