Of course my littler sister is completely ecstatic and didn't even hesitate to decline when I asked her to be my MOH, the only problem is she is currently located in Korea for the next few years on active duty. I'm so worried we will have everything planned out and it will be the day before her flight home and she will be told she has to stay for some reason and not be able to make it to the wedding. Last time she was on leave she was supposed to be home for a month and two weeks in she was called back and had to abruptly leave. What do I do if this occurs during the wedding? Do I ask one of my girls to be my "back-up" MOH way before hand to give the girl fair warning or just ask one of the girls last minute to step in if my sister needs to be absent?
