One other thing; even if next_personality() doesn't take in an argument,
since it's still a member function, you'll need to refer to a "self" as
its argument.

    def next_personality(self):
        ...

In C++, you might be familiar with the 'this' pointer.  It's the same
idea, but with Python, we explicitly show it as a parameter, just to
disambiguate things.
