Copper

I don't understand what the architects were thinking when they decided that copper would be a good siding for the school. I hate walking into a brand new school building that, on the outside, already looks like it is years old because of the now greenish copper. A bigger example of this is the Statue of Liberty in New York, which is a gift from France made of pure copper (except for the flame). Copper does, however, have traits that make it very water-resistant, but that doesn't seem to be an issue seeing as the sides of a school shouldn't be leaking anyways. I'll admit that the siding did look nice in the beginning, but I have mixed feelings about being associated with a school that looks like a rotting penny.
