Invitation.
Dear friends,
I have wonderful news. I have been accepted to the Shivaji Medical College Nagpur.
It is a time for celebration for me and my family.
That is why I would like to invite you to my party on January 15, 16:00, at the community center ballroom, located next to the main square, downtown.
See you there,
Anita
