Received an (admittedly handwritten) thank you card today from a friend whose wedding we went to last month. I thought it a bit off that it was a round robin message with no 'Dear...'; to paraphrase - 'thanks for your kind gift and for sharing our special day', especially as we put a lot of thought into the gift (sourced from an artist in another country as it had a connection to the location where they got engaged). What do you think?
