You can deny it, but in my childhood we were smarter. Simply adults do not listen to us. And if no one listens to you, then how can you be sure of his genius.?
And then the dual position. Genius - is the quality of the individual, not the individual. Personality you may recognize only the society / the other person. That is yourself you can not recognize genius. As you recognize objectively. But since you have is not the child, so you can evaluate yourself from the side and to plead, baby genius as an adult. This fact is an objective assessment? Is not it so?
