Another dream...a repeating dream...I'm back at John Rennie trying to resign but I can't find the office and...I don't know who the principal is...the building is rather like an Escher print...the one with the ladders...so far...I've woken up before I could actually quit! And of the course of the real irony is that I have been retired for 19 years...no wonder I don't know the principal! But...not one seems to know who the principal is!
