I turned invisible not long ago--
Thought I was seen; I wasn't, though.
Friends' eyes slip past, and when I wave and smile
They talk to other, closer friends for a while.
So then I sit alone, live in thin air,
Or, turning others visible, I stare.
I live in the clear space of a marble;
No-one else can see
The way that it is inside of there,
But that's what makes me me.
