Hi Knotties! I had a question regarding my FI's one and only sister. While she is only a few years younger than me she is in a totally different world. I'm a mom and have barely had more than a glass of wine in almost 2 years, she is a college student and still likes to party. Don't get me wrong, we get along and I don't care how she lives her life but we just aren't close. She's only seen our 8th month old maybe 15 times. I like hanging with her when we do see her, its just not often. My sister and mother thought perhaps I should ask her to be a BM, but I really wanted to keep our wedding party under 4 and my sister and 3 best friends fill those spots. My FI was married (very briefly--don't ask :]) 3 years ago and his sister was the MOH, even though she wasn't that close to his ex. I feel bad not asking her and I guess what I'm asking is if it's something I HAVE to do because etiquette says or if that's something that's flexible. Thanks for the advice! And sorry it ended up being so long!
