This is a very light question, I know. My boyfriend and I have lived together for a year. When we were running errands the other day, we picked up holiday cards at Target. We didn't send cards last year, but I love getting mail, especially holiday cards, and I think they're a nice gesture to our friends and family. When I asked my mother to check some addresses for me with her address book, she told me how odd it was for an unmarried couple to send cards! Would you be offended to receive a holiday card from an unmarried couple?
