I remember I had a flu back in year 6. I had running nose, high temperature and cough. It was one of the worst experiences in my life because I had to stay in bed the whole day and couldn't play video games or go out with my friends. The only good thing about it was that i didn't have to go to school. But I still had to do my homework.
