Host of a Home : Niche

They are all my home         Except where I lay my head

I
  Claw
Bite
   Tear
Gnaw
   Pinch
Prick
    Hollow
          And rip into whatever remains of human I can find
   I carve a home in them

One only I can escape without regrets

Some would call it
              Taking advantage of someone
I call it habit

What happens if they leave you?
     Well it's simple
Some homes just are not built to withstand an unstoppable force

I hate explaining this
Explaining is for those who have something to prove...

And as for me?
                    I'm just a parasite
