If you open it, close it
If you turn it on, turn it off
If you unlock it, lock it up
If you said it, admit it
If you can't fix it, call someone who can
If you borrow it, return it
If you value it, take care of it
If you make a mess, clean it up
If you move it, put it back
If it belongs to someone else and you want to use it, get permission
If you don't know how to operate it, leave it alone
If it's none of your business, don't ask questions
If it ain't broke, don't fix it
If it will brighten someone's day, say it
If it will tarnish someone's reputation, keep it to yourself
