So I checked out a movie called The Silent Twins which was based on a true story! The two twins are girls who seemed to communicate with each other but did not communicate with outsiders. They pretty much trained themselves how to not engage when people were talking to them and to act sick. They would eat slow,walk slow, and hold their head down they were also fascinated by cartoons and this continued on as they developed in life.
In the very beginning the girls faced abuse by their peers in school that was so harsh and disgusting. This movie had a lot of sadness in it and mental illness as well.
I'm left with feelings that parents really need to check on their young children in different environments and to make sure that your children know that there voice matters!
