In this film, Camille would usually keep all her feelings bottled up inside and not express it to anyone who is concerned. This is not good especially if you are in a relationship because for it to work and for your partner to know what is happening, it takes constant communication. Do not be afraid to speak up. This will only end up hurting yourself more. You will feel heavy inside and this will not make you happy.
Here are some scenes in which Camille just chose to keep her emotions to herself despite being hurt and having a hard time keeping it to herself
If you put a lid on a boiling pot, eventually the contents will rise to the top and spill over. Human emotions are no different. If we push our feelings down and down and try to avoid them, eventually, they will explode out more fiercely than before.
If we bottle things up, they don't just go away.
Emotions will stay down until we physically can't contain them anymore, then they'll burst out fiercer than before. And it won't just be that one feeling, it will be everything else that's been thrown on top of it since. For some people, it can be years, or even decades, or repressed experiences.
