My friend's daughter is getting married next year. My friend called me and told me her daughter wanted my DD (6) to be her flower girl. DD6 is quite quiet and doesn't want to be the flower girl. My friend said I should make her do it for her daughter. I told her I don't make my DD do things she doesn't want to do. In the background of the phone call, my DD8 was hopping up and down saying she would be flower girl. I suggested this to my friend. My friend said crossly, "She doesn't want DD8! She wants DD6!" I just told her, "Well, she can't have her." My friend is now not speaking to me and my DD8 feels rejected and has been grumpy with her sister in the day since this chat. I tried to explain to DD8 that she just wants DD6 because she is small and doesn't want an older child, it's not personal. I talked to DD6 and told her about getting to wear something special and she still won't have anything to do with it. So that's not happening. Did I handle this badly? Please tell me it will all blow over with the girls.
