Subject: Re: How do two objects communicate?

Thank you so much!

http://java.sun.com/docs/books/tutorial/java/concepts/
What Is an Object?
An object is a software bundle of related variables and methods.

What Is a Message?
Software objects interact and communicate with each other using
messages.

object communication through messages seems at the core of OOP, and yet
"observer" is not in my sams teach yourself ruby's index, it is only in
the reference section of programming ruby, 2nd edition. Same for send
which seems key to the example.

Why is something which is at the heart of OOP so little explained? I am
baffled. 

Thank you so much for the example, and all this info
