When beginning this course I asked myself why you would override the ToString() method. It sounded easyer to my just to make a new method like MyString(). Now I understand that this was the concept of polymorphism in action to give other People the chance to interact with my class in a unified way over a commonly known interface.

Very very helpfull!
