Again, Who is that Unknown Person?

"Nothing. You are just pursuing a thing of the past. And don't tell me that the reason you try to act friendly in front of everyone is that you want to fill up the void that Ariana created." I said. 

"T-That's…" He tried to counter my reasoning but he himself knows and has already admitted the fact but doesn't want to accept… not in front of me. Even I, myself, wouldn't want someone to figure out my problems, it's the worst thing that could happen to someone. 

Some might take it as a positive thing since they got to know about their shortcomings but this isn't applicable for everyone. Even if they agree with those critics, there is a part that takes a strong hit. There might be resentment towards the person, even a humble man doesn't want the other person to point out your shortcomings.
