I would like to tell you a few words about the last time when I was ill. It happened a month ago, when I came home from school. I had a high temperature, a headache and a sore throat for a few days and then I got a strange rash with itchy spots. When I came to the doctor, he said that I had chickenpox [chickenpox - неисчисляемое существительное]. Then he prescribed me some pills and asked to stay in bed for a few weeks.
