Yes, I don't know either.  I got this assignment for my homework, and
in UML diagram class ShoppingCart has method buy(), and the class
Buyer doesn't have any methods, only attribute ShoppingCart, and I
must simulate/implement online shopping.  In my world buyers buy too,
just wanna check with somebody with more experience.  :)

Thank you both.
