I don’t lose files from my computer - not only do I have automatic backups, I make periodic manual backups to optical media.
Paper copies can get lost, damaged by water or gnawed on by household pets.
I just got my mail. There were 11 items. I just threw 10 of them in the trash. All junk mail. I tried to get the post office to stop delivering it and was told they have to deliver it.
Everynow and then I write “Return To Sender” on the junk mail and drop it in the box. They want something to do? Send this crap back!
