I can't override the method in Son with the override keyword, but
without that keyword I can hide it! So I suppose that doing this:
Son oSon = new Son();
The result would be "I am an unruly son".
I don't want that, I want that all derived classes of Father return "I
am acting as a father" to the console, and I want the compiler to
complain if a derived class wants to hide or override the method.
Did I clarify things a bit more? Thanks for your response Raja.
