Achoo!
You're going to Machu Picchu?
No! That's just me sneezing.
Ew! That's terrible! Haven't you heard "Cough and sneeze, elbows, please"?
Wh. . . what? Why would I sneeze into my elbows when I can sneeze into my hands?
Because that is the easiest way to spread the germs!
I thought covering your mouth would help prevent the spreading of the germs.
Yes, but what happens after that? What about the things you would touch after that?
I hadn't thought of that.
Ideally, you should use a tissue when you cough or sneeze and wash your hands later.
