In the movie Trust, there is a character named Matthew, who is struggling because he seems to have an anger issue and has a bad reputation. Things aren't great at home, because his dad is always hard on him and always yelling at him or hitting him. In the movie, Matthew and his dad gets in an argument and Matthew says that he was "going to move out". His dad then laughs at him and tells him to clean the bathroom. Matthew's dad has the mindset that Matthew will never go any where and be stuck at home with him forever.
In the book, The Stranger, we see a common relatonship with Salamano and his dog. Salamano treats the dog poorly and yells and beats it on a daily basis. When the dog comes up missing a few chapters later, Salamano panicks and doesn't know what to do. In my opinion, he took out all the anger he had harboring from his wife's death on the poor dog.
Do you think there is a reason why Matthew's dad treats him that way? Is he scared of Matthew growing up? Is there something in the story that we have yet to find out?
