One day Miss Berry, my first grade teacher, announced that we were to have blood tests. In a few days we would go to the school nurse who would prick our fingers, squeeze out a drop of blood, apply it to a glass slide, and then we would go back to our rooms. It wouldn’t really hurt very much she said. Just a momentary pinprick. We must take these permission slips home, have them signed by our parents, then bring them back.
