I should have been more specific in my example.  The Load actually
hydrates the customer, not a theme.  Copy/paste error.

public Customer(int customerID) { ...
 ...validation...
customerDataAccess.Load(this, customerID);
}

so then, after something like:

Customer c = new Customer(123);

I could then access c.BillingAddress, c.BalanceDue, whatever else,
etc...
