Why can't you call a non-static method from a static method?

Question

I have a static method [Method1] in my class, which calls another method [Method2] in the same class and is not a static method. But this is a no-no. I get this error:

Answer 1

A non-static method requires an instance of the class. Unless you have passed in an instance, or created an instance in your method, you cannot call a non-static method, as you have no idea what instance of the class that method should operate on.
