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.
