Shadow Child

They are known as the shadow kids.
These kids are kids that hide all day long.
They were the third born.
So since they are the third born they will never see the light of day ever again.
They keep the windows shut and have the blinds closed.
They can not join family fun that is outside.
They think it is unfair that they have to hide.
They want this rule to be gone about the third child.
They want to have fun but they can't.
They can never have fun.
