Spending Time with My Father

My father is a serious person, and he is quiet most of the time. Every time I talk to him, he responds with only a word or two. For a long time I thought that he was hard to communicate with. However, the basketball game we both watched on TV yesterday offered us some common topics. We talked about the game and players. Now I realize that my father can be talkative if I bring up a topic he is fammiliar with.
