I had a different impression.
Mama looks like she has had a hard, hard life. She is in her 60's and looks 20 years older than my Mama who is 71.
I think she got there by way of the fist or the bottle. I did feel sorry for her. She works in a paper mill and Dad does not work. Who looked healthier?
Travis looked as mean as a snake to me. I looked at his face & his affect and had to trouble believing his fist ruled that house.
Interesting.....I just saw them once and would love to see the interview again so I could pay attention to some of the things everyone here has brought up.
