What could possibly go wrong?

摘要

In my previous business life I was an expert witness. In this capacity, I was called upon to review the work of other tradespeople and make a judgment call on the quality and craftsmanship of many defective hy-dronic and radiant installations. I've have seen things that would cause the hair on the back of your neck to stand up. Some of these things were silly mistakes made by good people who unfortunately thought that they were doing the right thing, only because they didn't know any better, or had not taken the time to become educated in their given field. Some of the things I saw were minor infractions, like leaving the balance of a 300-ft. coil of tubing sitting on the crawl space floor because they were told by their boss that the loops had to be the same length, plus or minus 10 Percent.
