My dearest Mohim,
First of all, congratulations on your big day! I wish you both a beautiful life full of love and happiness.
I know I should have been there, but due to some unforeseen circumstances, I was unable to make it to your wedding.
I disappointed you, and I feel deep regret. Please accept my heartfelt apology. I hope you will find it in your heart to forgive me for not being there for you. I promise you it’ll be a party when we meet next!
Your friend,
Mexrangiz
