Sitting around the dining table out the back one lunchtime the conversation of when you last visited the doctor came up, because you couldn't remember ever going.  We worked out the it must have been around 6 years previous, with an ear infection.  You were very funny and asked how we could all know that you were well if you hadn't been to the doctor in all that time!  You were around 13 then.  Over the course of the next 4 years you saw enough doctors to last you several lifetimes.
