OK, So Usage is the key abstraction. I dont understand how the shopping
cart is the use type. Purchasing would be the use case, I think. The
shopping cart is itself used. Otherwise, is the use type
ShoppingCartUsage? So the usage of the shopping cart is the thing we
are talking about. The Shampoo is what is in the cart. But what is the
relationship between the cart and the shampoo? Contains?

Why not "ShoppingCart contains Shampoo"?

I am slowly getting to understand this..
