I am going to a friends birthday that will happen to be on December 8.At the end of next month, so I will fly back to New York. I really feel sorry to lose this good chance to enjoy myself with you. Best wishes. Yours sincerely, John
亲爱的李先生，我很高兴收到你的来信。谢谢你的邀请。我想去你美丽的学校，但我不能。我要去一个朋友的生日，这将发生在十二月八日。在下个月底，所以我将飞回纽约。我真的很抱歉失去这个好机会和你一起玩。最美好的祝福你诚挚的
