They are creating their own style, an unfocused commitment [?] doing things in shocking ways. They [?] their hair brown, red, yellow, and blue. They [?] their skin until their complexions resemble those of California lifeguards. They chat noisily on phones in public, and they are rude. They cause trouble; a juvenile crime wave [?] spreading across the Asian countries. Schools once famous [?] rigidity and [?] have turned into chaotic places."
