Changing Worlds

You were small
Your world was tiny
I was your world
I wished to remain there as long as I could.

You grew up.
Your world changed.
I became a spec in your large world.

I watched you grow.
And wished to remain a spec
That you could return to
In times of need.

Years have passed by.
Sure I am a spec to
You do come to.
Now my world is you.

Whom am I saying this to
Who is saying this to me?
