Telling tails

I have recently treated workmate R's cat Jackson after he came home dragging his tail limply behind him. R is a married woman. We have this conversation in the prep room with Oz Vet working on something else in the background. 

R: "He's managed to get it up this morning! Almost halfway. He's still not able to use it properly though. You know, [husband] thought maybe he just slept on it funny and made it go numb..."

[Oz Vet's eyes have been getting gradually wider...]

R: "...so maybe that's why his tail wasn't right. Jackson does silly things like that."

Oz: "Oh thank God. I thought you were talking about your personal life!"
