Dear Lily,
Congratulations!I have got the news in the morning newspaper that you had graduated from Hong Kong University with a excellent performance.You always are committed to studying.
Since we haven't seen each other for several months,I miss you so much.Besides,you will go to America for farther studying,which means a long no see again.Therefore,I decide to invite you to have a dinner
together next week in VeeYa resterant.Would you want to come?I even can't wait for no longer.
Finally,wish you success in the farther studyding.
Yours,
