Do you typically call or write in a response card when you RSVP to a wedding invite?

* Social etiquette is to respond to the card and stamped envelope as to whether you and your spouse are attending the wedding, but, if one is away and can't respond it's best to phone the person. Remember, at a reception the Bride/Groom has to pay per place setting so it's important to know how many people are attending the wedding reception.
