Some say having nothing in common is the only thing we have in common. BUT, we do have something in common; we just need to take the time to realize it. 
For example: Every one of us experience this every day. 
Science calls it “Brain Grey” (ie: Eigengrau). 
It’s the color we see when our eyes are closed. 
Not quite black, not quite total grey. Close your eyes and take a look.
