.... in the psychological realm of this...
At what point do we see the difference between what is called "passive-aggressive" behavior and what is called "depression"?
When is an action truly "passive-aggressive" and not really to be understood as belonging to "depression"?
How does the interpretation of actions color how it is responded to?
According to this site, these are key traits of "passive aggressive" behavior:
(1) procrastinates,
(2) sulks or argues when asked to do something he doesn't want to do,
(3) works inefficiently on unwanted tasks,
(4) complains without justification of unreasonable demands,
(5) "forgets" obligations,
(6) believes he is doing a much better job than others think,
(7) resents useful suggestions,
(8) fails to do his share, or
(9) unreasonably criticizes authority figures
I have also read that passive-aggressive behavior is characterized by a kind of pretentious resistance. For example: one acts as if one agrees, but then in effect makes it impossible to go forward (by being reluctant to do what was agreed, by avoiding it, etc. etc.)

It does seem to dove-tail around ideas of being-productive.
And these are often related to issues of "depression" in other ways of interperting such 'sluggishness' and dis-interest.
