Overheard

Bradley: *coughing*

Chloe: You need to cover your mouth when you cough.

Bradley: But I just couldn't.

Chloe: If you feel your cough coming you need to turn your head or go into another room so you don't spread germs.

Bradley: Touche.

Chloe: What does "touche" mean?

Bradley: It means, "you're right - you got me."

...

Okay, then.
