In Wilson, Fences I noticed this passage:
Troy: Liked you ? Who the hell say I got to like you?
I feel like Troy was just protecting his son. He lived through a lot of discrimination and that may have influenced his choices in what he said and did concerning Cory playing football. I think however he could have been kinder to Corey, he was really hard on him. It may not be so clear to Corey that Troy really does love him.
