I don't think I'm the only guy who has felt bad because he can't play on a certain day and makes other players wait longer for their turns. If you're going to visit relatives or have a busy day coming, there should be some sort of option for you to skip turns. You basically sit out of the next round. When you get back you'll have the armies for the turn you skipped, but no card (duh).
Also, perhaps you could set a date to be skipped in all your games.
I think it'd be very handy for us civic minded folk who don't like others to wait or suffer because of us.
My set is a bone coat-of-arms and chandelier! How cool is that?
