-# Overview
+# 5. Inner Workings of Python Objects
 
-The inner workings of Python Objects.
+This section covers some of the inner workings of Python objects.
+Programmers coming from other programming languages often find
+Python's notion of classes lacking in features.  For example, there is
+no notion of access-control (e.g., private, protected), the whole
+`self` argument feels weird, and frankly, working with objects
+sometimes feel like a "free for all."  Maybe that's true, but we'll
+find out how it all works as well as some common programming idioms to
+better encapsulate the internals of objects.
 
-In this section we will cover:
+It's not necessary to worry about the inner details to be productive.
+However, most Python coders have a basic awareness of how classes
+work.  So, that's why we're covering it.
