It's pretty much expected that wedding guests bring a gift, right? Or at least a card? Out of the 50 or so people who came to our wedding we got 20 or so cards and gifts. Maybe I'm crazy but I just thought it was proper etiquette to bring something.... I don't even mind the people who traveled out of town or the people who helped with the wedding not leaving something, I'm just a little baffled by the rest.
