Yep, @kmakm - it has totally flummoxed me, too!!
I can't remember what my actual level was .... but it was reasonably high!! And I've only ever spoken English (tho I dabbled in French there at one stage .... and my French teacher resigned at the end of my HSC year - and i think I was responsible for it!! She moved to France to teach French Students, English!!) I can still remember her trying to get us to unlock the Classroom Door ...... 'Toc Toc - ouvrez la port!' No-one did!! LOL Poor little bugger! :( She was REALLY TINY - Her head didn't even reach the first window pane of the door, so we pretended we did see OR hear her! Gee we must have been naughty little buggers!! :(
And I STILL don't know what 'Grandfather Patients' are ..... no-one else has mentioned it! Only me!!
Fucked if I know!! :(
