求助一篇英语道歉信60-80词

你和陈先生约好在本周五下午进行商务会谈（business talk），可是你临时要去上海出差（on business）,要到下周一才能回来，请你给陈先生写一封60-80词的道歉信（Note of Apology）

Answer 1

we have not seen for a few weeks. A few days ago, I held a party in my house. There were a lot of friends coming to the party. We played games, sang popular songs and had a big meal. But I felt unhappy during the party, for I failed to invite my best friend, you. I write this letter to get your forgiveness for my mistake. I know you are fairly broad-minded.
To show my sincerity, I will have another party for you. It will be pleasant to invite you here.
