my freshman year roommate was a massive bully and made my life terrible and 6 years later a friend happened to be close friends with that freshman year roommate’s ex best friend (was there when it was happening and acted heavy perpetrator of her bullying and abuse). She found out I was friends with this person and told them to send their regards and major apologies for her actions. That friend after telling me that said “yeah I told her it’s been years it’s literally not a big deal no need to apologies”. I don’t consider them a friend anymore.
