I live in a house with many doors
doors that each lead to a plane inhabited by unknown creatures
thousands of monsters of the unknown

I make sure that each and every door is shut
to keep all those forbidden monsters away

Every now and then I hear knocking at my door
from a single monster
who I simply learn to forget and ignore

Because I am aware of the monster and his tricks
and know better then to let one in
because if you let a monster in

The monster will never get out

It's much better to tolerate a headache or two
then to spend an entirnity with a monster
who only wants to stay with you
