Why apologies to friends are harder to write than professional ones
Professional apologies follow a structure. Friend apologies don't have rules — which is exactly what makes them harder. You want to be genuine without being performative, specific without reopening the wound, and warm without being sycophantic. The prompt handles the structure; what you supply is the honest detail about what actually happened and why the friendship matters. That detail is what makes the message land rather than read like something you found on a greeting card.
The most important sentence in any apology
It's the one where you say what you're going to do differently, not just that you're sorry. 'I'm sorry I cancelled last minute' is an apology. 'I'm sorry I cancelled last minute — I've been unreliable lately and you deserve better than that from me' is an apology with accountability. The prompt pushes the AI toward the second version. Read the draft and make sure that sentence is in there before you send it.
