how about giving 'impressions' of your day? Things you've noticed...
lock yourself in a room with a big pile of puzzles. do the puzzles. occasionally, people call you on the phone and ask you for stuff. do that, then go back to your puzzle. That's probably the best I can describe it. The latest puzzle involves getting freeRADIUS to run on a SuSE linux box, so it can translate between a Cisco wlan controller and authenticate users to the wireless lan via LDAP to an eDirectory back-end. spending hours trying to find the missing "{" in the radiusd.conf file. Something is obfuscating the first character of the entered password to the letter "a". So, as long as your password starts with "a", it'll work.
I've worked shoulder to shoulder with programmers before... and this really does NOT make me shake in my shoes, partner. Sorry. And I actually can keep up with what you just spouted... so.
Anyway... when I did work with programmers, to relieve tedium... an occasional conversation would occur... between people working... pee breaks... coffee breaks... eye drop breaks... so... it isn't all think, think, think. Nice try.
... and this was one of THE greatest dilemma's in my M as well... becuz my xH did not 'get' what I did, wasn't interested in it... it's okay... but beyond him talking about him... nuthin.
So... I'd go off and find something to get into, cuz I like to talk about stuff... not just R stuff... all KINDS of stuff... and unless it was his work, sports, the kids, and sex... not much interest in anything else.
On top of that, he'd get huffy when I'd talk to OTHER people, go to book clubs... well sh!t, give me a break... you don't want to talk, fine... I do...
I understand being that mentally engaged all day, the last thing you want to do when you get home is mentally engage... but... it's part of the problem.
