How to stop being offended?

Incorrect perception. The same situation affects different people differently. It's not about who said or did what, but how we reacted and perceived the information. Calm perception without irritation is merely a matter of everyday 'training'. Essentially, we ourselves make the decision to be offended. As it's often said: 'Be offended with yourself...'. In difficult situations, repeat to yourself: 'I love myself and will not be offended'.
