i was eavesdropping

I was in the lobby of my dorm tonight and I was overhearing a movie in the background, and it was the kind of movie with a lot of dialogue ( I later looked at the screen and figured out it was the movie Garden State with Natalie Portman). At the time, I had no idea who was talking or what was going on, but there was a woman dominating the conversation, and I could tell just by her tone and her style of talking what kind of character she was. I sat and listened for a couple of minutes, and it was pretty funny, but I guess it kind of interested me how expressive the actress was for me without any visual.
