Comment on doing each of these things:--firing a bean shooter at anyone; throwing gravel or sand; firing off a cap or torpedo close to some one's head; boxing a person on the ear; running a nail cleaner or pencil point into your ear; putting on the baby's cap so that the ears are folded forward; asking your teacher to repeat her question. 7.
