Is it Bullying?
When someone says or does something unintentionally hurtful...they hurt you accidentally, that's RUDE.
When someone says or does something intentionally hurtful...they hurt you on purpose...but only once, that's MEAN.
When 2 people say or do hurtful things back and forth to each other, that's a CONFLICT.
When someone say or does something hurtful on purpose, over and over again, and in a one-sided way, that's BULLYING.
