Siddhartha took his son from the son's mother to live with him in the hut of his friend vasdueva.
He honored his mourning. Siddhartha understood that his son didn't know him, that he couldn't love him like a father.
The kid disappeared in the forest to find his way to the city going to his mother. His dad and vasudeva are still following him but they could't find him in the right time because he had already arrived.
After that siddhartha went back to the forest and laid on the ground thinking in nothing. Vasudeva then found him and tried to make him feel better.
Believe that's better for both of you, let's go to the hut.
Siddhartha waited for his son to understand him, to understand his love. One day, when Siddhartha the younger had once again tormented his father very much with spite. Vasudeva took his friend aside in the morning and talked to him.
