Strange

 No words but somehow a nano second glance of a stranger reminds you of an old friend in their entire essence. 

You dig deeper and after exchanging lengthy dialogue,  they indeed discover they have the same life philosophies as each other. But all this from a glance? So accurate a snap judgemental or pure coincidence? 

The trigger.  They both had the same teeth and aura.

Odd.  

No words.
