i think that somehow the reality of the other person actually being there is a necessary key. Sometimes I get CAD problems I can’t quite figure out, even though I know what I want, and I get a colleague to sit at my desk and push the mouse around, clicky-this, clicky-that… I find it easier to suggest solutions over their shoulder and I’m often embarassed that I’ve wasted their time calling them over…

but you know what? Hile I find that it’s the ‘obvious’ solution that I catch in 5 minutes… it takes me 2 hours to not find the solution all by myself. It’s not always enough to just pretend to have someone else look at your work.
