The context of the following conversation is Taylor's doctor diagnosed him with the flu but he was not careful about spreading his germs and he got Lee's son sick.:
Lee says You know, I'm really upset you got my son sick..
The friend responds I am really sorry-I had no idea I had the flu!.
Lee responds Doesn't matter. You've got to be more careful about spreading germs!.
The friend responds I know, but I had no idea I was sick! What was I supposed to do?.
Lee responds You should always be careful not to spread germs whether you think you're sick or not. Wash your hands, don't cough or sneeze on people. You know, normal stuff!.
The friend responds Makes sense. Never thought about it that way. So sorry..
