Apologies

Sitting so still,
You appear to disappear.
Into a world of make-believe,
Onto an island of fantasy.
I whisper your name.
So quietly,
Almost hating to disturb the place.
You've built into the wall surrounding you.
And you don't even hear me.
I can't say,
That I blame you,
For wanting to escape;
Only that I envy you.
For being able to.
