Another Box Concept

I am in a box. I know I’m not ready:
I peaked, it’s bright, though blinding.

Something has put a mouse in here, and it was irritating
And gross at first but then

Friendly, so I allowed it
To chew the corners. I know no one’s name

From here, so I’ve named the mouse
The same as me and we’re planning

On leaving together: I’ve started
Chewing too. I’m designing us both sunglasses.
