From the Inside Looking Out

Sometimes I wonder
Whether I might disappear - 
Immediately
Forgotten when out of sight,
I am The Silence
(like the Doctor Who creature, 
only not evil),
Or a house elf, unobserved.
Would they draw a mark
To remember I exist?
Would they knit a hat
For me, so I could be free?
What would I do then?
I don't want to change the world
I just want to know
That yes, I matter.
