Dear Mary,
How are you doing? I am sorry that I was unable to attend your birthday party last weekend. Please accpect my sincere apology. The reason why I missed out your birthday party is because my working roaster changed in last minutes due to aircarft technical issues. I was trapped in Japan so I can not come back to Hong Kong on time.
I hope your had a great time to celebrated with familes and friends. I want to celebrate with you, may I know are your free on the coming weekend? I will book your favourite resteraunt and I hope we will have a amazing time for celebration.
Please reply my email so I can arrange it.
Best,
Angie
