I am so sorry that I couldn’t attend your birthday party, I just have a lot of things going on and I’m trying to keep my family safe during this pandemic I hope you can understand my situation, although I wish you a happy # birthday, have a great day.
One way I would write a letter on why I couldn’t attend someone’s birthday
i apologize for my absence from your party. i couldn't show up because i wasn't finished with my 40 hours of violin practice. unfortunately, your party schedule badly collided with my practice time. obviously, i chose practice over celebrating your birthday. maybe next year i'll show up with a gift.
