Me: …did you know there was a genetic component to lupus?
Me: Yes! I read about this in one of those articles about all of the armadillos in the Southwest that are giving people lupus.
Him: . . .
Me: Here, let me… wait, have I been saying lupus? I mean leprosy.
Him: Oh! You have been saying lupus. I did know about leprosy.
Me: How was I getting those two words mixed up? I must be tired.
Him: Well, they both start with R.
Him: Wait! No. But they do in Japanese!
