Not directly related to survival items , but related to the principle itself. Yesterday my DD needed a copy of some document for the school. I am a busy guy and even a simple reuqest like that stresses my nerves , however being a prepper I relaxed and told her to wait a minute until I retrieve a copy which should be nearby.

I checked my work bag. Sure enough there were copies of several documents, but not that one. I opened the trunk and grabbed the trunk bag where I was sure to have a copy. Again, there were other copies of different stuff, but not that one. Apparently, I used up those copies earlier and did not put any more.

Yesterday, I made TEN copies and scattered them around in the work bag , trunk bag ..etc. Today, my DD isn't going to school, yet I am not saved that trip. I have to go to school just to give them the document ... It's last day to submit the document or else she won't be registered for next year.

If I had the copy yesterday, I would have saved myself big hassle.
And it is not even a survival item.

Morale of the story : TEN is one, one is none !!
