I always think it’s far fetched in crime shows and books where they find some hidden code that the victim has written and it leads them to the murderer. However today I had a look through the notes section on my iPhone. I wasn’t aware I used it so much and there are lots of seemingly random codes in there. If I’m mysteriously murdered, police don’t waste your time! Unless I’ve been offed by a disgruntled bookmoocher whose postage I underpaid. If so, good luck matching up my abbreviations and weights!
