A father knows his son
A father will always love his son even when no words pass between them. He will always understand that he is difficult to communicate with. He just wishes that his son is still little and he can tell him things that won't be questioned. He knows that he might have let down his son many times without even realizing it. There will always be gaps between a father and a son but he wishes there were ways to bridge these.
Such is life and he just hopes that he has given his son enough hints about his thoughts and intentions and how he has lived his life in the hope that these may as guideposts, lead him to where he will be happy. Being stern and forcing the issue will only widen the gap and create animosity and rancor in a heart that may have been disillusioned.
Here is a website to show how much he loves the place where he was born. May it serve to open a similar love in his son.
