I don't expect a thank you note. People who have just gotten married, had a baby, or just graduated are crazy busy and I don't want to get the obligatory thank you note just because they are "supposed" to write one. I would rather they spend their time doing something more productive than sending me a piece of paper that I am just going to throw away. It is nice to get a verbal thank you or to see their excited looks when the open the gift but the thank you notes, if written, always seem a little forced. We usually do verbal thank yous unless I know someone is going to be offended if I don't send a card.
