- 1.1. LouAnn-Sue-Lyn has been brought to the ER because when her friend Anita Ride came over to see if she could borrow Louann’s car, she found her friend with her bad foot (it had become badly ulcerated over the last few months) up on the table and it was looking really bad and stinking. The physician ordered HBO therapy, and after figuring out that it would not entail watching television Louann began treatments.
