When someone says something is their “favorite” tv show / movie / album / book / whatever, I assume they are knowledgeable about it. In fact, I assume everyone is as obsessive (or at least somewhat as invested) as I am about the things they like.
Instead, this is typically how these conversations play out.
Them: I love The West Wing, it’s my FAVORITE show.
Me: Me too! Who is your favorite character? Favorite season?
Them: Oh, I’ve only seen a handful of episodes, I’m not familiar with all the people. But it’s a great show.
Me: *blank stare*
