Apology Letters to Friend.
Missing Your Birthday Party Invitation

I want to sincerely apologize for not letting you know about my neighbor’s birthday party tonight. I realize how frustrating it must be to feel left out or uninformed about plans that might involve our social circle. It was thoughtless of me to assume you would automatically hear about it through other channels. I take full responsibility for not communicating better, especially given how much we value our friendship. I recognize that this may have made you feel excluded, and I want you to know it was never my intention to hurt you or diminish our bond. I should have reached out sooner and made a point to include you. To prevent this from happening in the future, I will make a conscious effort to share information about gatherings and events more proactively. I value our friendship deeply, and I want to ensure you feel included and appreciated. Please take all the time you need to process this. I genuinely hope we can discuss it further when you’re ready, as I would love the opportunity to make things right and continue enjoying our friendship. Thank you for your understanding.
