A large white envelope arrived at our house yesterday, from the Church of Jesus Christ of Latter-day Saints, addressed to Daughter #1. As of this writing, she is going to sit on it and open it in Relief Society on Sunday. To annoy her father. Daughter #2 thinks this is silly and an attention-seeking behavior, that the opening of a mission call should be a family affair, and that she should open it on Friday evening. It's #1's decision.
The RS Presidency has given Daughter #1 full permission to open it on Sunday. They think it will be a bonding experience, and that all those who are present will be more apt to write to her during her mission.
