Elsa is your sister. You along with your family went for a marriage yesterday. Tomorrow you have planned to go to the beach. Early morning your sister is shouting like anything. She suffers from earache. Many times you advised your sister to clean the ears after taking bath. She never took them into account. Since you are a doctor, treat your sister patiently. Apply spray on the ear and clean the dirt with the sponge. Wipe the blood using the specific instrument. With the instrument at hand find out the root cause of the problem. Remove all kinds of dirt from the ear.
