"So since the person living next to me already has a mental illness, why do you say that I also have a mental illness? Can everybody just get mental illness?"
"Then can I say that, in fact, everyone in the entire world is mentally ill, and most people's mental illnesses are the same, thereby excluding us who have a minority mental illness? So, are you discriminating against us?"
"No no no, that's not it, your mental illness is harmful, severe."
"Alright, as you can see, whom have I harmed? I could manage the mental hospital better than the director here. Whatever the director can do, I can do the same and even earn more love from the mentally ill, so, my severe mental illness equals director? Then can I say that it's the director who is really mentally ill, and I, am the director."
Ah, this...
Wait a minute...
My brain is going to explode...
"You, you make sense, and you seem very normal right now, but no matter what, you are mentally ill!"
