Made me think emotionally. OMG made me cry while watching few scenes.
The lesson that parent's try to teach every special kid is depicted here :
You know that you are special and it's not just you who is struggling to make the situation right. The people around you are going to make you feel bad as you are not like one of them. But don't fuss about them, there are more good people around you who like you to be around you than bad people.
Think about your parents, your siblings and everyone in the surroundings who is trying to help you. Parents have dedicated their life for you and they would do anything, literally anything to make you feel normal. They have struggled very hard to bring you up. They did not fuss about it.
Think about your brother/sister, for them getting ignored has become a norm, because you always needed special care. Your sibling did not fuss about it.
Teaching a kid who is special is going to be equally special.
They are going to be a 'norm' only when they realize it themselves, be patient enough to teach them that.
