Some dumpster divers find personal journals and diaries while d-divin. I have not. If I ever do find any, then there will be the question of whether to read it or not.
Reading another person's chucked out journal or diary is not too cool to them, but I might do it if the chance arose. I would still know it to be a possible emotional violation against the journal writer. But, if it got chucked out intact and you or me read it that's the breaks.
I have to confess here that I do look at some personal papers and have read portions of notes and letters from dumpster loads, but it did feel a bit creepy. The strangest time was when I found printouts from graphic emails exchanged between two twenty some year old women who had some serious desires to tie men up and torture them for sex thrills. They also wrote about their fantasies to get the government to have contests to see who can come up with the most unique torture techniques to use when executing convicted criminals on death row. And the contest winner gets to do the torturing. When I read that the piece of paper dropped right outa’ my hands and back into the dumpster--but I was laughing inside at the time. I got that stuff from a dumpster in my apartment complex and was aware of who the woman was who threw the stuff out. She could have walked out her door and seen me there. I'd never tell anyone who she was, unless it was buddy of mine who was about to go have sex with her.
I did realize right then and there at the dumpster that evening that it was some great material for a scriptwriter or novelist. But I threw it all back in the dumpster anyway.
I got some cool stuff in that load though. She was moving out at the time and had thrown a bunch of Rock n' Roll memorabilia in the dumpster. I'm an old Rolling Stones fan type of guy, but she had Aerosmith type tastes, so I sold her collections of Rock n' Roll buttons, pins, knick-knacks, photos, and posters at the flea market. I did give my twenty some year old niece first choice on that load though; that’s my style of dispensing d-dived goodies. Me first, family and friends second, charity next, what’s left is up for sale.
