This should often be the case: Your coworker will not let you go into a presentation when you are emotional or livid about something.  They tell you to pull yourself together first; compose yourself and compose your objects that I say.

Of course, I am not the only one.  If you are familiar with our friends, the Gang of Four, you have already heard this mind-bending concept.  Make your objects connect to each other via well defined interfaces and hide their implementation.  This is a sound, modern software practice.  In fact, I just spent four days this past summer listing to speakers take composition for granted at the architectural level.  They were assuming (not all of them of course) that composition and abstraction is a skill that is taken for granted by most developers.  We know, being the folks in the trenches, that this is not always the case.
