Flo is around 60, married to Eb since she was young.
Flo wears blouses, dresses, pants, white socks, tennies, she's maybe had a facelift from a few years before when she was thinking about leaving Eb. She is socially ingratiating; a little afraid she doesn't measure up. She grew up in a family that struggled financially. Her mother is still alive -- kind of ignorant, religious, old-fashioned. Flo is conscious of this. The mother has dementia to a point one would surmise she is brain-dead -- grunts and other sounds come out of her which prompt Flo's sister to say that the mother wants her to have the money.
Flo and Eb have adult children. Her child-rearing days were defined by her last child, a girl, a juvenile diabetic who required great care. Eb did not help but only talked proudly of how Flo handled the situation.
Flo often sneaks a glass of wine in the bar when Eb is not looking.
Flo's role in life has mostly been to take care of Eb, even when there were children to take care of. Flo has had to be Eb's buffer against the world.
