A lot of early Rhodies were "naughty" - this was, after all, a nation who proudly self-identified as rebels and rogues, cowboys who didn't cry and worked hard, but knew how to party. I know my ancestors were thus, and even my parents generation (my dad, who got really drunk for the first and probably only time at his bachelor party, was a comparative nerd, but then he was an academic who then became a judge, so...).

Also, you've made me want to read Doris Lessing now.
