My wedding is still two years off and my mom keeps asking me to have my sister as part of the wedding party. My problem is that I have already asked all the girls I want to be in my wedding party. I didn't ask my sister because one she has absolutely no personal hygiene whatsoever. And she is slowly going blind so she wouldn't be able to see to walk. Is there something else I can ask her to do that would help me out just as much?
