I have 3 bridesmaids: my sister and 2 friends. My sister has been doing all of the work and paying all of the money for the shower. It's one week away and one of the girls hasn't done a thing. My sister told me that I shouldn't worry, that they'll come through but she's been doing everything. The other two have made no initiative to do anything at all. This bothers me. If I were one of their bridesmaids I would be bending over backwards for their special occasion, what do I do?
