Dear [recipient's name]:
As you undoubtedly know, Jack and Donna Smith will celebrate 25 years of marriage on June 15th. In recognition of this exciting occasion, we are planning a surprise party (yes, shhhh, don't spill the beans) in their honor. We will be getting together on Saturday, June 29 at Highlands Club for a dinner party from 6 to 9:30 p.m. We would love to have your family join us.
Feel free to bring gifts and cards. If you'd like to offer a short toast or say some special words in front of the group, that would mean a great deal to Jack and Donna.
Please RSVP via e-mail to [[email protected]] by June 8, and let us know how many will be attending. Hope to see you at this special anniversary celebration, and remember, it's a surprise party!
