I watched it for the 2nd time and thought the mother was jollying everything along just too much. I really felt she was trying to put a brave face on it, but if she hadn`t laughed, she certainly would have cried. The British `Stiff upper lip`, came to mind.
I felt the daughter showed her true emotions and was going along with her mother`s show of bravery, to humour her, but was, at times, shocked and very upset.
I feel a bit judgemental writing this, but don`t want to be. I just wondered how much was for the cameras.
