Ladies I really need your help on this one! Here's the scoop.... my sister is a few years younger than me and at that age where she thinks the world revolves around her. We don't really talk but since I'm getting married I attempted many times to ask her to be in my wedding. I called and left voicemails, sent texts, and sent messages on FB but all attempts went un-answered. I told my mom, whom she is pretty close with, to ask her for me but still she said nothing. NOW, with 107 days till my wedding, my sister is asking my mom "am I in the wedding?"......REALLY!!!! Now I don't wanna seem rude but i have already ordered the BM's dresses and my mom is tryna play the good guy and CREATE a place for my sister...ie- she can carry your train. I don't know what to do now...if anyone has any ideas I am accepting ALL suggestions. Thank you so much, best wishes

You know she won't accept all suggestions. Also, someone says "Make her a reader" and she replies that she doesn't know what that means. I've never been to a wedding without readings - though admittedly, I haven't been to many weddings. What is hers going to be? Just vows and rings? Every "ceremony" in the Big Book of Wedding Time-Wasters? What?!
Also - I didn't have to order BM dresses, but isn't three months plenty of time to just order her a dress?
