I wasn't really raised in a household that celebrated Christmas. However, at this point in my life, I both give and receive Christmas gifts. But because I'm fairly new to this, I've realized that I'm unaware of one basic thing: Do you send thank-yous for Christmas gifts? I gave a gift to everyone who gave me a gift, so I guess I thought that the exchange kind of cancelled out thank yous, but I'm usually a big thank-you card person so that doesn't make sense. I just want to do the polite thing.

Do you write thank-yous for Christmas gifts? What about for cards?
