Hi Alan,
I would like to say Thank You of inviting me to your Birthday Party. It's been a long time for me to go to a friend's party, so I really had a great time. I am also glad to know so many new friends in the party, like Sally, Bill, and Tom. We shared a lot of interesting topics and personal experiences. Thanks for introcing them to me.
I hope you enjoy the party as well and please say Hi to your friends.
Ok, I wish you a Happy Brithday and take care.

Best,

John
