Why didn't I read this sooner?
Passive-aggressive behavior refers to passive, sometimes obstructionist resistance to following authoritative instructions in interpersonal or occupational situations. It can manifest itself as learned helplessness, procrastination, stubbornness, resentment, sullenness, or deliberate/repeated failure to accomplish requested tasks for which one is (often explicitly) responsible. It is a defense mechanism, and (more often than not) only partly conscious. For example, suppose someone does not wish to attend a party. A passive-aggressive response in that situation might involve taking so long to get ready that the party is nearly over by the time they arrive.
