Dear James,
I hope this message finds you well my friends, James. I am writing this email to inform you that I am not able to come for your marriage anniversary party next Saturday. Firstly, I really appreciate that you were invited for your amazing event, and congratulations for your wedding anniversary as well. Your inviting was so fascinating to me, and I wish to attend with all of my gratitude.
Regrettably, I am overseas because of the business trip which was scheduled suddenly, and I expect that this will take over 1 week or more. I tried to optimise the date for this trip later from your party, but I could not, regarding it as an important task that I must succeed in. I apologise for absent and ruining your feeling on such a amazing day.
However, I suggest you to have a dinner together after I come back from my business trip, when is Monday, 2 days after your party if you do not mind. My flight will land around early afternoon, so we can meet around 6pm.
Finally, I apologise again for missing your upcoming event, please check this letter and reply me if your possible to have dinner with my on monday. Hope we can make it.
Regards
June Young Kim
