Antonio and his two friends were busily working their tincture set. The proper use of a tincture set was something of a social art, it required composure and grace and foresight and attention to detail. The junkies had none of these qualities. They were awkward and rather clumsy and yet terribly determined. They were deeply intoxicated, so they made many small mistakes. Whenever they made a mistake they would retreat and try to think about it, and then they would mentally circle back to poke and prod and jiggle. It was like watching three little spiders gently preparing to eat a trapped and kicking insect.
