The traditional animals/shapes/cars/etc. examples all use objects to represent actual things. But sometimes, one's objects don't reflect anything that you're trying to actually model. The need for them has just sort of arisen from the way the code has structured. They don't represent anything as such, they're just a way of putting in some extensible runtime dispatch. And it seems like people often prefer to use conditionals rather than objects for this situation. Not really sure why. Perhaps most people think of mere objectness as having some meaning, that makes using an object inappropriate for this kind of situation? I'm not sure. If you keep an eye out for this, I'm pretty sure you'll start to spot it!
