Dear [recipient's name]:
Well, friends, it's one of our favorite times of the year-Cinco de Mayo! Let's all celebrate together by gathering at El Rodeo, our favorite Mexican restaurant. We'll be meeting at 6 p.m. on, of course, May 5th. I've already checked, and El Rodeo will be having specials on all their appetizers, entrees, and margaritas that day.
Please email or call me by May 2nd and let me know whether you can join us. Then I'll make a reservation for the group. Hope to see you then!
Sincerely,
[Signature]
