Chit-chat

"Honey, you are keeping me alive," the elderly husband says.

"Quit complaining. The alternative is not that great." 

"Do you think I'm losing my memory?" he asks.

"Well, you can always make new ones."

"Why don't you forget stuff, Edna?" he asks.

Her name isn't Edna.

"I don't know, Roger." His name isn't Roger.
