Apology Letter For Being Tardy
Dear {Recipient},
I'm so embarrassed I arrived {number of minutes} late to our {activity} last {day of the week}. Please accept my sincerest apologies.
I should have done more to make sure I would be on time. Instead, I got lax and failed to take into account {the reason why you were late}. I'm sorry and I'll do my best to make sure it won't happen again. Your time is valuable and I respect that.
Please let me know if there's anything I can do to make it up to you.
Sincerely,
{Your Name}
