In the eighties when I was in grade school, a classmate named Scott did a show-and-tell about his diabetes. He pulled out his syringes and testing supplies. With a bulky blood sugar meter, he tested his blood, took a shot, and explained what he had to do each day to control his blood sugar. I went up to get a closer look at the table of supplies. I remember seeing all the needles and thinking, "Thank God I don't have that."
