 Why is Sara upset when her dad asks her to read the article about solar panels?
Up until then it just seemed like constant warmth, as though she didn't have any childhood concept of Dad apart from him getting home from work, then her sitting on his knee, eating cookies and watching football highlights until Mom came in and scolded them both for ruining their appetites before dinner. Dad is in the bathroom, and Sara has had enough of Fox and whichever war this is. In her pocket her phone vibrates, purrs against her skin, reminding her it's there, making sure she's not forgotten where her real friends are, that there's a world outside, beyond Dad and his TV. Sara works for a non-profit in Brooklyn that helps big organisations to transition to renewable energy. Godammit Sara, are you telling me you hate advertising now?
 There is an implication that she's not informed about the job she does every day
