You might not want to watch movies with me.
Well, don't watch movies with me if I've a) seen the before or b) know a lot about the subject material. I have a horrible habit of providing running commentary. (My poor, poor husband...)
For example, this week, we tossed on The Day After Tomorrow. This is no masterpiece, but we do love disaster flicks and this one ranks at the top of our rewatches. In about fifteen minutes, I talked about a continuity error I caught; my love for the librarian who is still working; how one character, in reality, would be called "Doctor" and not "Professor;" and the impossibility of a freighter making it that far through city streets. My husband, used to this, mostly smiled and nodded.
I have no idea what drives me to do this. Maybe I just want to talk. Maybe I feel like showing off. Maybe I think my commentary might enhance understanding of the movie. I just seem incapable of not talking when I think I see something interesting.
To my credit, I (usually) don't do this with new movies or in theaters.
Still, you've been warned.
