Social rejection occurs when an individual is deliberately excluded from a social relationship or social interaction. The topic includes interpersonal rejection (or peer rejection), romantic rejection and familial estrangement. A person can be rejected on an individual basis or by an entire group of people. Furthermore, rejection can be either active, by bullying, teasing, or ridiculing, or passive, by ignoring a person, or giving the "silent treatment." The experience of being rejected is subjective for the recipient, and it can be perceived when it is not actually present. The word ostracism is often used for the process (in Ancient Greece ostracism was voting into temporary exile).
