It takes all kinds...BUT

 I truly believe it takes all kinds. 

I've tried to write this four or five times.

Unfortunately, some kinds are "subtracted from the equation". 

And this happens, often enough, 

to make one not sure what "IT" is. 

I give you no context, as a gift. 

Each of you who read this 

will have a different  all kinds

a different subtraction

and a different "IT".
