In the meetings that I run with people who are approximately my level, no one talks more or less than they need to, everything is completely sorted out in about 15 minutes, and everyone leaves with a clear idea of what they need to do.
In order to give the appearance of preparedness, I like to show up with a messenger bag full of stuff. It's like no matter what question they ask me, I could - at any moment - whip out a reference manual, a scale, and a calculator and MATH1 right there on the table.
In truth, all I have actually brought to the meeting is a set of plans printed out on 11x17 paper and the writing utensil that was closest to my hand when I left. I do not put these plans in my bag because my bag is full of unrelated crap, and I am afraid that when I pull the plans out, things will go flying (see previous entries on losing stuff and lack of organization).
Things actually in the bag: planner, journal, unsent postcards, tampons, keys, sunglasses, somewhere between 2 and 73 gum wrappers, gum, sometimes a broken watch (I like to think of it as Schrödinger's watch in that it is both there an not there at any given time), business cards, and receipts.
1In lieu of actually MATHing, I say things like "It's all very complicated, I'll send you the spreadsheet" and then wait for the look of panic followed by a polite refusal of said spreadsheet. It doesn't even have to be a spreadsheet, sometimes I say "code section" or "email from the city" or "shnarfle2" and it elicits the same response. People like to know you did the work, but they don't want to know the dirty, boring details.
2I made this word up. Right at this minute. You never what's going to happen here; it's craziness.
