Someone mentioned in another thread writing TY notes for Christmas gifts. I have always done TY notes for an event where I am the one receiving but not giving gifts (i.e. b-day, graduation) but have never done them for Christmas, because 95% of the time I was *exchanging* gifts with the gift giver. I've also never received a TY note for an Christmas gift I have given. Have I been rude all this time? Just curious what people do.
