I am the maid of honor in a wedding for one of my dearest friends. One of the bridesmaid is a friend of ours who has lets say "changed" a bit over the years. she has become completely unpredictable and at times makes terrible scenes of anger in public. I am very nervous that she will do something off the wall at one of the wedding events. I dont want to discuss this in depth with the bride so she is not worrying about it. Any advice PLEASE!!!!
