so I guess it's a thing for some people.

can't imagine what though...

It actually seems innocuous as just a calendar on the surface...so it must track something that mattered to him...could be hanging with the cool kids ?

Or people reliving their glory days.

in their code are reminders of his "conquests"

I’ll bet Mommie kept them for him. Loving momentos of ‘the boy.’

She writes in them daily. There's a big stack of them in a bookcase. Occasionally, she consults them. It's a habit for her and a way to recall activities on any particular date.

She says I can read them if I wish, but I don't. She doesn't care, one way or another.

I keep almost no records, although I have all of my emails, outgoing and incoming, since 1995. From time to time, I search them to find a bit of information and its exact timing. I've been using remote email clients since that time, so they're stored on those servers, somewhere. If they disappeared, though, it wouldn't really matter.

And we must accept it due to the extreme volume in which he presented it

in math classes. It's also a debate technique that's useful when your case doesn't have a leg to stand on.

He SCREAMED that Trump's inauguration was the biggest ever PERIOD!

A high school student who is so convinced he's going on to great things that he keeps all his papers with his future biographers in mind? Someone with a mild form of packratism?

My husband keeps and files any papers that come with appliances and gadgets, although he does get rid of them when we no longer have the item. And we do go through the papers periodically and get rid of things we no longer need. If there are any old calendars around the house they're ones that fell behind the filing cabinet and have been forgotten.

Especially if his parents have a big house. It's easier to shove everything into a box than to go through it all and figure out what to keep and what to toss.

how he straightened his nameplate on the table and his papers several times before sitting down? Obsessive/compulsive for sure, with a bit of anal thrown in for good measure.

OCD/anal retentive and throw in control freak.

“Oh my god really! seriously that guy has a problem”

But I would keep none earlier than that.

I was at her house helping her organize her voluminous piles of paperwork, and there was a random piece of paper with only a name written on it. She'd not throw it away, it might be important. She has old bills 50 plus years old, kept in case someone tries to "come back on" her. I'd guess she has calendars well older than this one. Some people are just horders.

In this case, however, it seems interesting that he was able to produce a 36 year old calendar almost immediately.

She's in her late 40's, but she has records and journals from when she was in HS. She likes to look back and she what she was doing, how she was feeling - and how she has changed.

It's sort of how she sees herself in the world (as a writer, and an introspective thinker)

chock full of workouts and studying and everything else is coded; skis, ralphing, beach, etc. that would be pretty meaningless to his parents. Why he kept it? Who knows, maybe he's just a packrat, maybe he was proud of his handiwork.

Needs reminders of the "good old days"?

High school stuff went away at some point during college. College stuff went away at some point after being married and living on my own.

…. did it to track my exercises/work-outs, finals & midterms. They ended up in a box of school stuff. My mom saved it... as a preteen mom or someone threw away some comic books of mine. I was so distraught, I think she decided not to throw anything away. Mom saw the comics as "Funnies" newspaper - read and toss... there are a few gems in the box of school stuff.

into their Yale archive...

Psychopaths who get a thrill when looking at the calendar with hidden messages.

She is a type a personality. I'm a type z and can't find a receipt I know I kept from last week.

They are small day-minder type books. Easy to keep.

They came in very handy when I went through the process to get a security clearance. I needed to know every trip I took out of the country, with specific dates, locations, and contacts made for the past 10-20 years (I think).

I would have beed dq'd if she didn't have those books.

Interviewing the parents will shed light on this. Why was he grounded?

in a small duffle bag that somehow made it through all my moves and travels, going back to high school. I guess I thought it would be fun to look and reminisce someday. Last year I lost my home to hurricane Irma and I was packing up any salvageable items when I ran across the bag. I briefly scanned the items which felt more like a journey through a dusty old attic than anything pleasurable, and hoisted them in the dumpster, 50 years later. One less thing my kids have to toss someday.

..when mom passed last yr I went thru 50 years of crappola in her house. Lots of my HS stuff....which I read and tossed...except for my Beatles Bobble Heads. I told hubby im gonna see some of our crap on Antiques Roadshow!

..I kept track of my very young dtrs school events and impt appts as well as my college events and tests on it as well. I have them all rolled up in a tube somewhere. When I die and my dtr has to clean my garage she will get a kick out of reading them....for about 5 minutes.. then she will toss them. Maybe thats how Judge got facts for his books and whatever it is he does. what the hell DOES he do where he needs a publicist?......and speaking engagements?...about what?

their memoirs.

I’m just a nerdy engineer and not a judge, but I still have every tax return I ever filed going back to high school over 50 years ago. I also have the daily , weekly and monthly planners I have used since high school ( mostly the DayTimer brand.). I also have kept a journal on and off for the last 50+ years.

I don’t think it was as rare as some younger people think.

but if I worked for the FBI I would suggest a forensic exam of the documents for evidence of recent provenance...
