“Do away with the opinion ‘I am harmed’, and the harm is cast away too. Do away with being harmed, and harm disappears.” Marcus Aurelius, Meditations.
‘Sticks and stones may break my bones…’ What is considered to be a harmful remark or comment is up to you. Even if someone does offer you insult or offence intentionally, or displays disregard or rejection, how you interpret it and react to it is up to you. Opinions and thoughts are not facts.
