We had to explain to them what a three-dimensional, you know, lock-up page was and why, you know, gutters were a certain width and if you had column rules and gutters, you know, why they were centered  and why you couldn't, if you had a wide margin below three columns of text why you didn't move the gutter beyond where the text wasn't so white, or why you didn't move it down and have it join a rule here because it would have been a real pain in the arse to have to do that in metal, so you just sit and do it.
