I don't even think that's passive aggressive.That seems naturally occurring in most humans....when I say passive aggressive ...I mean by example:I may sulk...and you ...perhaps see somethingis wrong...but you've no idea what...and earlier ...perhaps I cooked for every one.Well,you may have said something was "cold ...or too salty"...in my head I am hurt.I took is as a slight, thinking... "Geez...a thank you might have been nice." Instead I give you a cold shoulder.What I should have done...was to say..."Feel free to warm it in the microwave",and realized it may be colder than you like...or "Oh...I guess it might be a bit salty." Rather than get all hurt over it. So...in essence...you don't behave direct...you kind of...insinuate that you are hurt...and,half the time...people don't even realize they did anything.All they see is a mood shift.I reeeeeely make me mad when I do that.
