Premise for the film "With out"

After viewing the film “Without” I have came to conclude that this film could have a variety of different premises. I would say one of which could be blind trust leads to destruction, because the family left the house with that teenage girl trusting her to do everything proper and to take care of the old man. However, she abused their trust by doing things that were inappropriate. Another premise could be how great love defies even death, because the main character was sort of mourning over how her friend committed suicide because she was unhappy. Still, beyond those two premises I’ve came up with I would say many scenes in this film raised a number of questions too me that were left a little bit unanswered. For example, the scene where the main character has her male friend over and they drink, and he starts putting moves on her but she kicks him out. Then there was the other guy that she went on a date with that was apparently going out with the girl who worked at the coffee shop. On top of the old videos the main character had with her friend on her phone, when she was commenting on how she loved her breasts. I found myself asking was this girl lesbian or straight? how did the girl from the coffee shop know she went on a date with that guy? who was the other guy that came over that night and put moves on her? There was also a scene where she looked in the mirror and saw a strange scar on her back. Which had me asking myself how did she get that scar? One scene that really got my mind altered was when she had the dream of the old man being perfectly normal and eating breakfast when she woke up. Regardless of all of these unanswered questions I still found the film to be quite enjoyable and it did have some meaning about love and death. I noticed that the main characters attitude and mood changed drastically after she had visited the mother of her friend that had committed suicide. Shortly afterward, she is confronted by the girl from the coffee shop and slightly beaten. Then soon after that the family returns home outraged by the minor things the main character forgot to do. I can definitely understand at the end why she just starts bawling, all of these instances combined I think would be overwhelming for anyone. From seeing the mother of her dead friend, too being nearly attacked by someone she barely knows, then getting an unpleasant lecture from the family’s house she was watching. Despite all of these things I personally think that she was just conflicted without love, whether she was lesbian with that girl who committed suicide or not. She in my opinion felt that no one would fill the void of that girl she was close with that killed herself. Great love can defy even death.
