What is the main idea of the story below?

Mathilda Wormwood was a brilliant and extraordinary young girl who had the power to move things with her mind! Her favourite hobby was reading. Unfortunately, Mathilda’s parents thought books were a waste of time and that she should watch TV instead just like her older brother. They neither understood nor appreciated Mathilda, which made her feel like there was something wrong with her. Due to this, Mathilda felt lonely at home, but she loved visiting the library to read and to get away from her family.

At school, Mathilda was one of the most intelligent and kind students in her class. Her teacher was named Miss Honey: a caring and selfless woman who loved to educate and support her students. Miss Honey adored Mathilda and Mathilda adored Miss Honey. Miss Honey was one of the few adults who made Mathilda feel appreciated and understood. She always encouraged Mathilda to believe in herself.

Unfortunately, the headmistress of Mathilda’s school was Miss Trunchbull: a cruel and selfish woman who terrified her students with the horrible ways she would punish them for minor things. She was the opposite of Miss Honey. Miss Trunchbull always made the students and teachers feel bad about themselves by putting them down and telling them they weren’t good enough, especially Miss Honey and Mathilda.

Mathilda and Miss Honey decided to do something about Miss Trunchbull. They devised a plan to expose Miss Trunchbull’s cruelty using Mathilda’s powers. Once Miss Trunchbull was exposed by the whole school, Mathilda was celebrated, not just for her powers, but for her intelligence and kindness. Mathilda helped people realize that, just as it is important to be kind to others, it’s important to believe in yourself and to be kind to yourself even when others aren’t.

Afterwards, Mathilda decided to live with Miss Honey. Her family didn’t understand why Mathilda was happier with Miss Honey since she didn’t even have a TV! It didn’t matter to Mathilda. She was so happy being in a loving and supportive home with Miss Honey where they could read together.
