Because of an ear infection, Little Johnny, had to go to the pediatrician. The doctor directed his comments and questions to Little Johnny in a professional manner. When he asked Little Johnny, "Is there anything you are allergic to?" Little Johnny nodded and whispered in his ear. Smiling, the pediatrician wrote out a prescription and handed it to Little Johnny's mother. She tucked it into her purse without looking at it.
