Dad started to feel unwell last night. When Mom went in to check on him and found him shaking underneath the covers; this is their conversation.
Mom: “What are you shaking from?”
Dad, shivering: “M-m-malaria.”
Mom, mostly sarcastic: “Well, you were down in South Louisiana last week. Do you think you got bit by a mosquito?”
Dad, still shivering: “Y-y-yes.”
Turns out he has the flu.
