OT: A man takes his wife to get tested

Two days later, he gets a call from the clinic.

Doctor: "I'm sorry to inform you that your wife's results were mixed up with another patient's. We're not sure if she has COVID-19 or Alzheimer's Disease.

Husband: "So what am I supposed to do now?"

Doctor: "Take her for a long walk and leave her. If she finds her way home, don't open the door!"
