Marla

This ... chick ... Marla Singer... did not have testicular cancer. 
She had no diseases. She was a liar. 
I saw her at "We Shall Overcome,"my melanoma group Monday night ...
 at "Seize The Day," my tuberculosis group Friday night.
Marla -- the big tourist. The faker.
With her there, I was a faker, too. Her lie reflected my lie. 
And all of a sudden, I felt nothing. With her there, I couldn't cry.   
So, once again, I couldn't sleep.
