Some people feel sick in the winter.Many people get the flu.How do you know when you have the flu?Do you have a sore throat?Does your nose hurt?Do you have a headache?If you have a fever,you might have the flu.
Don't worry!If you are sick,see the doctor.Take some medicine and drink hot drinks.Stay in bed for a few days.You will feel better soon.
