OK, for both 姊妹 and 兄弟, we need a day for doing rehearsal in the chapel to make sure the run-down will be smooth. The exact date is not yet determined, but it would be about 2-6 days piror to our big day. One thing, though, the day for rehearsal is most likely on the weekday. I will try to make it around 4pm so that we don't need to take too much time off from our cubical farm.
