Maybe. Or maybe you have some discomforts about the topics - for example maybe deep down you feel that perhaps you waste too much time watching TV, and should be doing something more productive with your time, and feel a little twinge of embarrassment or guilt when confronted with someone else's better example, so you don't like it when they talk about their own situation of not owning a TV, and want them to shut up, even though they aren't directly criticizing you.
