英语作文：假如你是MiLei圣诞节、新年即将来临,请给你的好朋友Jenny写一封信,想她祝愿圣诞、新年快乐.词

现在有电话和网络,为什么还要写信哪,须说明理由.我给的理由是把她的电话号码给丢了,然后再祝她,节日快乐,比较好. 下面是我代你写的英语信,不知是否满意.
Dear Miss Jenny,Dec. 20th, 2010
How I miss you! Are you very busy with your study(work)? How are keeping these days?
I wanted to phone you the other day, but unfortunately I lost your phone number. So I am now writing to you to ask you for your phone number again. If you can receive this letter, you may phone me back. My phone number is 10022456879.
By the way, Christmas Day and New Year are coming. I wish you a Merry Christmas and a Happy New Year in advance.
Looking forward to the pleasure of hearing from you.
Yours sincerely,
MiLei
