“Everyone is unique” is a fact that most people easily forget unconsciously as their grown up. This is due to human’s nature to differ individuals that is too different from others. In human society, most uniqueness are only allowed in childhood, but it “have to change” when you start to enter adulthood. This uniqueness is something that to some extent only one or a few people can have. Uniqueness is different for every people, there’s no way two exactly uniqueness can exist at the same time, even if it can, it is very rare. But two or more “similar” uniqueness can exist.
It’s true that not all uniqueness can be accepted in society when you reach adulthood, but that doesn’t mean that it have to change. Human doesn’t accept someone who is different from them in to their circles of society. It’s a good mind set ‘only’ if you make it to cast away bad things or bad people. Applying this to all people is gonna end up making this world/human society gradually losing it’s “colors”.
People change, environment change, all changes in this world, including the ones in the future, makes everything can be important. Like a chain of life or the wheel of life, some things like, your and other’s uniqueness may not be essential now. But it can be in the future. So people, don’t reject them. Try to understand them. Accept those unique people and their uniqueness. As long as it doesn’t make other suffer or losing something important, accept it. It wont do any harm to do just that you know.
