I'm finding a useful metaphor that resonates with my students is the fast food franchise, or really and chain store, petrol station chain or whatever.
class KFC: """defines how long to cook the chicken in what batter, also signage, branding""" >>> restaurant_on_sandy_blvd = KFC(lat_long) # from Google KML file shows a specific restaurant getting stamped out by the cookie cutter class template. Here in the USA, we define ourselves in terms of strip malls with franchises. "What's America without White Castle?" Or at least that resonates with some people. Organized religions work the same way. Kirby
