okay so i just booked the hair and makeup for my girls and I. I thought that i would let my soon to be sister in law (who is not a BM) just in case she wanted to get her hair done. well she was all fussy with me saying well why didnt you book an appointment for me? and she was also aggravated saying that since she is going to be at the hotel where the wedding is she might not come since the BMs and myself will be at my parents house and the hotel is 30min away. what do i do with a sister-in-law who should do her own hair, for its not her day its mine, plus my own sister is even doing her own hair. How should i handle this situation?
