Bridesmaid status achieved

So my best friend, Sammi, is getting married in April and I am super excited for her. Today I went and ordered my bridesmaid dress.  It is all becoming very real.  I am headed back to KC the first week of April for the Bieber concert and to see her get married. Can't wait to see her face.  I am glad she video chats me as often as she does otherwise i'd go crazy.  This will be my first time as a bridesmaid and I am co-maid-of-honor.  I was in my sisters' wedding but I am not sure what my role was exactly, I was only 11.
