How to Apologize by David Larochelle

5.0

Basic, to-the-point, and an absolutely necessary skill. There's no good reason not to apologize if you screwed up: not if they owe you an apology, not if the offense was a long time ago, not even if it was an accident. Being sincere is clearly covered, as is not making excuses.

And honestly, even if you have nothing to do with the offense, an apology can still be beneficial.
