What is a girl?

What is a boy?

 

You may simply answer

The gender you were born as

Or your clothes

      your looks

        your voice

 

But these things

Simply do not define

  

You may say

It's because girls can have children

And boys cannot

 

In seahorses

The males give birth

 

Then you may say

It's their aggression

 

Look at hyenas

The females are practically monarchs
