Answer:
Social Anxiety, Traumatization
Explanation:
You see a lot of schools give warning to kids who behave badly in the classroom, kids who don't do homework, kids who don't participate, etc. Well parents have to sign these warnings. This could either lead to 2 things. Child abuse, or isolation. That can give a child no matter what age trauma. In other cases social anxiety too. Kids will start to believe that the world is extremely bad and they will start to have trust issues which will slowly develop to not talking and then social anxiety.
