It's the same right?

Last nights conversation:

Patient...we'll call her Ms. M

(Ms. M)... My doctor told me I had an "erotic disorder" today. Do you know what that is and can you explain it to me?

(Me)... Wow! I'm not sure I've heard of that one! Are you sure it wasn't a "Neurotic Disorder"?

(Ms. M)....Oh yeah, that sounds about right. It's all the same right?

(Me)....Not quite...but I'll be happy to explain it to you.

.......that was after I composed myself and quit laughing.
