When Sue comes home from work, she gets changed and takes off her makeup. Sue is not concerned with her appearance, as she is not going out for the rest of the night. When Sue returns home from work, she is in her stage.

When Sue returns home from work, she is in her back stage.

Explanation:

Backstage can be described as anything which is originally occurring in the back where the audience cannot visualize it.

When Sue goes to work, she knows she has an audience and she has to represent herself in front of them. As a result, Sue gets all groomed up. But at her home, Sue knows that there will not be anybody to observe her. Hence, her home is a backstage for her.  She gets all comfortable there and does not care about her looks at home.

i'll just take the points xd
