EACH behavior violates another person's emotional or physical boundaries and is therefore a form of "abuse". At the root of abuse, whether it is obvious to the abuser or not, is an intent to dominate or control another (bullying), be superior to or have power over another and results in "oppression". Oppression is a very painful experience for a victim, be it child or adult.
Identifying abuse when it happens can start change. Say things like: "Name calling is a form of verbal abuse." "Rolling your eyes at someone is emotionally abusive." "Interrupting is a boundaries violation." Once you start your "boundaries watch" you may discover behaviors that aren't included here! For additional boundaries transgressions that are specific to adult relationships see "Boundaries Transgressions in Adult Relationships."
