When you eat lunch, always wash your hands for 20 seconds to get all the germs out and don’t share drinking cups because another person has used it.
Wash your hands often with soap because when you wash your hand just with water your hands won’t be clean properly and that's why we wash our hands with soap.
When you use tissues put it into the bin and when people are coughing stay away from them or if they are sick that's why you wash your hands and stay two meters away from people.
