So I asked my sister to be my bridesmaid thinking she'd be excited for but with the expectation that she would make every excuse under the sun -- which she did. I eneded the conversation with her saying "Well, think about it and get back to me." After mulling over the conversation for 2 days, I'm wondering if I should call her back up and explain that if she's not excited to do this then I don't want her to feel obligated.
(And the majority of her excuses were about money, which really is not a problem for her. I mean, yes, being a bridesmaid can be expensive but she could afford it if she wanted to.)
