Passive-aggressive behavior is a pattern of expressing your negative feelings in an indirect way — instead of openly addressing them.
People who are passive-aggressive appear to agree with the requests of others. They may even seem enthusiastic about them. But they don't perform a requested action on time or in a useful way, and may even work against it. In other words, they use nonverbal behavior to express anger or resentment that they can't express verbally. An example is "showing up very late to a meeting that you didn't really want to attend and then making up excuses for your lateness that deflect attention from the real reason you were late. "
Signs and symptoms of passive-aggressive behavior include:
1. Resentment and opposition to the demands of others
2. Complaining about feeling underappreciated or cheated
4. Stubbornness, sulking - be silent or childly refuse to talk or smile to people that made u angry.
6. Memory lapses
7. Sullenness - angry or unwilling to smile
9. Cynical attitude - believing other peoples are not sincere
Although passive-aggressive behavior can be a feature of some psychiatric disorders, it isn't considered a mental illness. Researchers are studying how to classify habitual and problematic behaviors such as passive-aggressiveness. If such behavior is troublesome or interferes with your relationships or daily activities, consult a therapist who can help you identify and change the behavior.
Remedying this behavior can be difficult: efforts to convince the subject that their unconscious feelings are being expressed passively, and that the passive expression of those feelings (their behavior) invokes other people's anger or disappointment with the person, are often met with resistance. Passive aggressive individuals will frequently avoid treatment claiming that there is no way to remedy it. Since the effectiveness of various therapies has yet to be proven, these individuals may be correct. Passive aggressive disorder may stem from a specific childhood stimulus.
