Siddhartha What is Siddhartha father's final decision for Siddhartha? Why do you think he made this decision?

In the end, Siddhartha's father acquiesces to his son's wishes and allows him to leave. He also tells him that he is welcome to return if he is disillusioned with the Samanas. I don't think that Siddhartha's father had a choice. Siddhartha waa stubborn and stood on the same spot for two days until his father relented.
