I think many readers are about the same as me when it comes to backups: It is not only guns, knives and first aid, but also things we use every day. From pens and notebooks to handkerchiefs to whatever small tool or artifact you need to carry your everyday duties at work.
As silly as it may seem, many people do not understand the idea of having a backup, even though they have experienced the problems of suddenly being without that object that is common but needed in the performance of their duties.
One of the hard lessons I learned is that you cannot be generous. More than once, I have helped a coworker with his loss by lending him my backup, only to never see it again or get remunerated for it. Add insult to injury when the same person comes to you later asking for another back up and you have to do your best to smile and say you are fresh out when in reality you want to comment on the possibility that his birth doctor dropped him half a dozen times on his head immediately after delivery.
So, my advice for the day is: Have backups & don’t tell anyone.
