It’s not that one shouldn’t talk to strangers but individual that are a bit too strange. They actually have the characteristics of “creepy” more then different and you can tell not just by what they say but the mannerism behind such words. The strange one’s are the individuals who appear hidden from the rest of the group by their own dark choice. Withdrawn in a world where just as a snake snaps their bite they look for their victim’s first words. For if one doesn’t talk to strangers they may never meet anyone in the 1st place but if one talks to the strange they may never have that chance to speak again.
