Still need an officiant, a florist, and some kind of music. We've already got a caterer and a photographer. Um. Sam, you need a suit. So do the groomsmen and best man. And the maid of honor and bridesmaids need dresses. I guess then, maybe...some kind of hair and makeup session? Do you have to do that? And then there's the cake, but that shouldn't be too hard. And the registry and gifts and the rings and the parties and the honeymoon.
...You know, I wasn't this stressed reading the baby books. I think I'll go back to that.
