Fully normal (man)

You are of the opinion that you're entirely normal?
And you discussed that with that other person in your brain?
That other personality confirmed that you're normal?
Because yet another being inside the same brain is of the same stance, I'm normal?
Congratulations: Definitely, when they and you all agree, the only true conclusion can be, you're all "normal".
Audience: Please define what is "normal" ....
