> When learning Object Oriented Design in a school setting, the discussion usually goes something like this:

> “This is a picture of a dog. What things can a dog do? Bark, eat, run, walk, these are its methods. What are some things that describe a dog? It is soft, brown, has 4 legs. These are its properties”

> “Purely behavioural code should be kept at a minimum at the boundaries of your domain layer, mostly to interface with the richer world of Nouns.”

> I like to refer to this object modelling advice as “Find the Nouns”, and it is wrong
