“Pop-Down” rule
The reciever knows it’s class
The flow of control jumps around different classes
No matter where there code is executing the receiver knows its class and does the messagemethod mapping correctly for each message!
Example
Receiver is the subclass (Grad), executing a method in the superclass(Student)
A message send that Grad overrides will “pop-down” to the Grad definition as in the case of getStress() )
