I'm working on our thank you cards from our wedding and I'm stuck on how to word one particular thank you. We invited a family that I know, and their son was the only one who came. I'm closer with him than I am with the rest of his family, but we still invited his mom and step dad and sister. So how do I thank my friend for coming but say how we wished the rest of his family came? I put this one off until the end and I'm having a bad writer's block. I just want to make sure I say the right thing without sounding mean or awkward or anything.
