In Britain, you're branded a gun weilding, petty theiving, knife carry lunatic until you turn 30. Then you buy a top hat and a monocle, wear a burgundy dressing gown, smoke a pipe, and drink nothing but scotch and tea.
But yeah, not really a problem here i suppose, older people tend to have a kind of fear instilled in them from teenagers, think we're gonne mug them or whatever. Weird, since when i think about it, nobody i know would.
