Actors on a lawn asked  questions

They have no answers for.

 Blanks,

 Their next part has not yet been written

 Their past ones nearly forgotten,

And when and why a tangle of chaos to them.

The audience cheers.

They are a known quantity.

 They are in fact every part they have ever played.

Does the mirror ever stop reflecting?

And when there is no image what does

The mirror become?

I am because I know you see me

Without you I don’t exist.

But do you lie?

Yes, you do

Because you are a cheap mirror.
