My FI and I found ourselves in an Etiquette disagreement in these past few weeks, since we've been writing Christmas thank-you notes. I was always taught that it was proper to write a note for any gift that was received, weather it came in the mail, or was given in person. His family wasn't big on thank you notes, and he insists you only need write one if you haven't seen the giver in person, or talked on the phone to thank them. My question is, am I right, or is he? Should thank you notes be written for a gift no matter what, or only if you haven't thanked the giver through any other medium?
