My new concern is that it will rain for the party. I went from being not worried to obsessive in no time flat. The Weather Channel only predicts as far as 10 days ahead. As of right now, it's going to be partly cloudy on Friday (the day before my party), and scattered storms that night. It's too early to see the forecast for Saturday (and it's highly likely that the forecast could change in 10 days anyway).
I liked it better when I wasn't thinking about the party.
