Stefan and I love to visit you and Doug in SF!  We know how busy you are between your projects, your work, your children, and your many friends.  So don't think that we take it for granted, and do know how much we appreciate all the time you make to be with with us when we are in town.

Happy Birthday from Stefan (who just discovered text messaging - so adding a post to a blog is way advanced for him).  He wants to know when you're going to visit us again - this time in Germany.
