Teenage waste products

OK, I know I'm painting with a pretty broad brush here, so it'll be easier, not to mention a helluva lot faster, to exclude the good teenagers of today's generation. Each of us (hopefully) knows at least one. I'm fortunate and know probably a dozen or so. We know these kids and young adults and we know that they are a joy to be around. They make good neighbors, good employees, good students. . .
