Hey, meryl, that was a good observation about TS2, shot with the campfire in the background between their two faces. I almost missed that post where you pointed that out!
Also, Mikeala, you bring up a good point: how they hold their cigarettes. In my neighborhood, there were two ways: with the fingers over the cigarette, which was the "rural" or "cowboy" way and with the cigarette perched between the index and middle fingers, which was the citified way. The latter hold was good for use while driving a car, but the cupping hold was better if you were on a horse or out in the wind, to protect the flame from going out. Well, I'll just have to watch the movie again to see how they hold'em and then we can extrapolate the meaning from it.
