One a day, plus iron

There are lots of things that elude me. I have a lot of trouble telling faces apart. I get lost easily, even when going places I've been to sixty million times before. I can't carry a tune to save my soul. My art is... it'd have to improve to be "primitive". But there are some things I can do and one of them is the stupid ass "lock" puzzle that's going around on facebook like it's hard or something. It is not hard. A lot of people don't seem to know how to approach these puzzles, so Imma break it down for you, step by step.

( Before 2002, this sort of puzzle was an entire section on the GRE. I am mentioning this for only one reason, one patently obvious to the sort of people who need absolutely no help with this kind of problem. )
