A Pet Banana

My Mother has had 2 strokes and has Auricular fibrillation called A-fib for short. Which puts you at risk for more strokes. She also had a TIA which is a transient ischemic attack also known as a mini-stroke. On the way to the hospital during this episode she was trying to describe how she felt and said a pet banana was in her chest.
Later I asked her if she remembered talking about a pet banana and she told me the story about how she always wanted one and would wear it on her chest like a pin or brooch!
Here is our rhyme/story A Pet Banana.
