Saying sorry
What to write in an apology card
In an apology card, say clearly what you did, take responsibility without excuses, and acknowledge how it affected them. Then tell them what you’ll do differently and leave the door open without demanding forgiveness. A short, honest apology is far stronger than a long explanation.

Short and simple
For smaller things: a forgotten birthday, a missed event, a sharp word.

Heartfelt
For a friendship, a family rift or a partner, when it really matters.
Lightly funny, for small slip-ups only
Only for minor mistakes between people who already laugh together. Never for real hurt.
Formal
For a client, a customer or a colleague after a mistake at work.
Do
- Name what you did in plain words. Vague apologies sound like you’re not sure what went wrong.
- Say how it may have made them feel: embarrassed, hurt, let down, worried.
- Tell them what will change, and only promise what you’ll really do.
- Make an offer to repair it if there’s a practical way, like replacing something or rescheduling.
- Give them space. Say they don’t need to reply right away.
- Write it while the regret is honest, but not while you’re still angry. Sleep on a draft if emotions are running high.
Don’t
- Don’t write “I’m sorry if you were offended.” It puts the problem on them.
- Don’t follow “I’m sorry” with “but.” Everything after it cancels the apology.
- Don’t explain at length why it happened. A short reason is fine; a defense is not.
- Don’t bring up what they did wrong in the same card.
- Don’t ask for forgiveness as if it’s owed, or set a deadline for them to respond.
- Don’t use humor if they’re genuinely hurt.
How to write it
Begin with the apology itself, early and plainly: “I’m sorry I didn’t call when you needed me.” Don’t build up to it with three sentences of context.
Show that you understand the impact. “I know you were counting on me, and I left you to handle it alone” tells them you see it from their side.
Then look forward: what you’ll do differently, and an open invitation to talk when they’re ready. Sign off warmly but simply, with “With love,” “I’m sorry” or just your name.
