There's such a thing as *too* informal

Earlier this week, we got a cute and breezy e-mail from a friend inviting us to a combination Shabbat dinner and birthday party for her husband. Since both of us are still a bit under the weather from our recent bouts of bronchitis, we waited until the last minute to be sure we were well enough, and called just last night to say that we were coming. Imagine our surprise when we got a phone call this morning at about 10 minutes before 7 saying that the party is not tonight! I checked the e-mail, and sure enough, the sender had neglected to include the date of the party (not to mention their address). You might want to watch out for that, the next time you send invitations.
