A chocolate cookie (we'll call her Ann) went to a store. She purchased a small mammal for free. The mammal was intended to replace another of Ann's possessions - no one really knew what it was, but it was very shiny. She had owned it from birth. Ironically, both the shiny thing and the small mammal constantly produced smaller versions of Ann.
Later in the day, Ann began to shake violently. Someone picked her up and began talking to her. Ann instantly felt better and stopped shaking. Later in the day, she started to shake again, but only very briefly - she had stopped for at least fifteen minutes before the person came over and checked on her.
What a day for Ann!
Can you explain what exactly occurred during her day?
Please include an explanation for each relevant detail. The bare minimum is to identify what each object/person in the story is in reality.
