Subject: Invitation to join my sister's birthday party
Hi Biva,
Writing to you is always a great pleasure for me. You'll be happy to know that next Thursday we're going to arrange a birthday party of my younger sister. Though it's nothing special and a big one, I like to get you here. My parents also want you to be here with us on that day. Hope you won't miss it. Accept my invitation.
I'm waiting for your reply. See you soon.
Lovingly yours,
Jarin
