Mr,Paul
i am writing to invite you to my 20th birthday party next Saturday.And i hope that you can come since there will be a lot of friends that day and i am sure you will enjoy yourself with our interesting programs.
Firstly,we have a dance moment at 9pm,you may meet Harry,our old friend.We haven't met each other for years and he has just come back from Korea i think you two have a lot to share and talk,you know he is always a funnu guy.I have a lot of girls so i bet it's a good chance to know new friends and you may find someone interesting.After that we can enjoy our birthday cake together,it may be around midnight.
Please come and join with us next Saturday.Looking forward to your coming .
Yours
Maria
