Carol's hair is natural throughout except for when she hangs up a coat in the closet. When she's in the closet her hair is in a ponytail.
As Carol greets Florida at the door the toast she is eating appears, disappears then reappears.
Florida decides to quit on Friday and before she leaves for the day, she gives Carol a message from the school principal saying that he will meet with her tomorrow. The next day is Saturday, so school would not be in session.
Not only is her hair in a pony tail but the rest of her hair is freshly done. Her make up is brighter. Next we notice that Maud has WAY more eye shadow. Obviously this scene was shot on a different day.
