Mommys Girl - Catching Mommy Sneaking

In the living room, Gia Derza is eagerly waiting while sporting a glum expression. Christie Stevens, her stepmother, enters through the front entrance all suited up for a night out. She tries to silently tiptoe through the living room with her shoes off, but Gia catches her and stops her. What was her stepmother doing outside after sunset?
Gia is unimpressed as Christie makes up story after falsehood. Christie is embarrassed. Christie finally acknowledges to Gia that she went out dancing with friends. Christie was on the lookout because, despite the fact that Gia's father is kind to her, there are some things that he simply CANNOT give Christie.
