This is true. Today we received a punch list for a house we built last year. Among the items: "Mantel above fireplace gets warm after fireplace is on for an hour."
Of course, there are a thousand similar stories. Granddaddy told me the best one I've ever heard, about a local contractor who built a guy a house here in our town of abundant pine trees. A few months after closing, the owner called to complain to the builder that pine cones were falling from trees all over his yard.
The builder explained that this is normal behavior for pine trees and advised him that the problem could be solved by cutting down all of them but otherwise there is no way to make pine cones stop falling. The owner turned him in to the Better Business Bureau for not taking responsibility for the situation.
