.... By design, the purpose of a constructor is to properly construct the objects and rely on the fact that after the constructor is called, it is properly constructed.

Which means that without calling the constructor this is not ensured. So this is not acceptable. To avoid this unacceptable situation, the constructor is always called when constructed an instance. That includes when constructing the instance of a subclass whose superclass has a constructor.

[charred drum]

so we want to just make sure that the superclass has been set up correctly before using it's properties / methods in the child class constructor. Is this the right way to put it?

yup
