My favorite was actually the one about the carpenters/house builders (forget the name of it, I need to dig it out of some box in the garage and read it again)
I don't know if I liked it more then Soul Of A New Machine but for some reason House stuck with me. I remember a bit that talked about building to a "good and workmanlike manner." It's funny the stuff that sticks with you.
Yeah, I bought that and SoaNM as a pair because my parents had copies back in the day. Never regretted it and went on to read everything he wrote. Will miss the opportunity to dive into some subject I know little to nothing about with him.
