People are not on this earth for a long time. Don't hold grudges once you've accepted the apology.

A small mistake doesn't break trust or the relationship. It is the intention behind the action that does.

Don’t assume that others know that you’re upset. Explain why their actions made you upset. That will make the other person understand.

Forgive honestly.

You're still angry over that action? They're already over it and have moved on. So, who’s really suffering in this equation?

Dwelling on things causes unnecessary stress. It can make you sick too. Take care of yourself.
