Only if you know why

Update about my internal conflicts.
He saw me when he came out from seminar, and he stunted.
He stopped for 5 seconds and can not move his eyes from me.
I moved my eyes away but I was curious why he looked at me so long, and I found he was seeing something else, cause he did not realized I looked back to his eyes.
He stood still and then he regained consciousness.
Then he acted normal again, and I can feel he was uncomfortable with my existence. 

I worry if he saw non-human creatures again?

I will continue what I want to do, nothing can stop me now, no matter what they say.
