Suppose you are black and you receive a perfectly nice letter from a person you fell out with when you learned they were racist. You never made up and they never apologized for their racist comments. However, they ask you for some some news about yourself, and share some news of their own. How do you react?
You scrunch the letter in a tight ball and throw it in the bin.
You reply by telling them you are still awaiting an apology and a change of mind from them.
You do as if nothing happened and give them some news about yourself.
