It doesn't help that OOP is still frequently taught in a similar style; not necessarily with UML diagrams, but with inheritance hierarchies that are often based on physical objects (i.e. an Animal class, with Cat and Dog subclasses). This doesn't necessarily reflect current OOP's actual usage (tending towards less use of inheritance, as well as classes that represent more abstract entities like UI components), but it's the first exposure of OOP for a lot of people.
