I once had to say that to a clergyperson who was preparing to go to South America to build homes "for the poor" and wasn't entirely sure how to hold a hammer. Yes, that's right. It's not bad enough to live in a third-world poverty center, but you also have to live in a home built for you by some well-intended and maladroit American who doesn't know how to use common, and rather ancient, building tools. Buena suerte, mi amigo.
About a year ago I was asked to mentor some high school students who wanted to build guitars. Let's just say that between their non-existent work ethic and the manual dexterity of fish, I'm in no danger of losing any business to them. They faded away after they realized that a guitar takes time and patience to construct.
Anyway, I ran across this Canadian article that, I'm sure, could easily be translated into an American experience, too.
