What are some tips for writing a good apology letter?

When writing an apology letter, start with a statement that accepts responsibility for the wrong behavior, acknowledge the consequences of the wrongdoing, and offer restitution. Keep the letter short, gentle and sincere.

An apology letter does not have to recount the action for which the writer is asking for forgiveness. It seeks to make the recipient feel validated and to show that the writer recognizes the wrongs committed. It should use regular words and avoid making suggestions as to what the recipient can do after receiving the apology. A good apology letter offers a way to rectify the mistake committed and avoids infinite words such as "never" and "anything."
