Getting Ready for Kindergarten, Modesty, and Misunderstanding

Five-year-old Cy went to the doctor for his kindergarten check-up and immunizations.  He wasn't happy about the shots, especially when the nurse told him he had to pull his pants down to his knees.   He got 4 shots; one in each leg and in each arm!  That's cruel and unusual punishment! 

Later that night, Mom told Mr. Cy and seven-year-old Miss Em to put on their pajamas.  Cy reminded her that he needed to remove the band-aids covering his shots.  Mom, who was nursing the baby at the time, told him to come to her and she'd take the band-aids off for him. 
He looked at Em then back at his mother, "Mom," he said confidentially, "remember? I got the shots in my private area?"  
With wide eyes, Em said in horror, "He got shots in his nipple?"
