Do you always read the handbook?

‘You know what your trouble is?’ he says when we’re under the bridge, headed up to Fourth. ‘You’re the kind who always reads the handbook. Anything people build, any kind of technology, it’s going to have some specific purpose. It’s for doing something that somebody already understands. But if it’s new technology, it’ll open areas nobody’s ever thought of before. You read the manual, man, and you won’t play around with it, not the same way. And you get all funny when somebody else uses it to do something you never thought of. Like Lise.’
