My two daughters became engaged within one month of each other. The weddings are being planned a year apart. Of course they are at this point in each others weddings, but there is always drama over you stole my idea, blah, blah, blah. One daugher is much more headstrong an zilla-like. As the mother, I fear the worst, she won't be in her sister's wedding, either because she has made life too miserable and has been relieved of her duty or in a fit of rage refuses to be in the wedding. They have been spoiled growing up, but I always thought I didn't favor one over the other, always buying "two" of just about everything. I hear a lot of it's always all about "her". What's a mother to do?
