The uncanny valley man in street keep staring at but they won't respond, he can only wave hand all the time because he look scary, he won't stop staring at you and he won't respond but I have to warn you

Sign: do not stare at him back or he will haunted your house and If you saw him, look away immediately

Sign: He won't stop staring at you, he won't respond, all he can only do is waving hand
