I second the above story...I was never sure about the houses I got invited back to until Prefs...Prefs cemented one choice that I knew I would never belong in that house and did not want to diminish their sisterhood, but totally changed my opinion on another chapter and would have definitely accepted a bid from them...things were meant to be and the timing was not right as well...as a religious person, I knew God did not want me to join at this time.. I don't know about you so I won't make any assumptions, but I do want to wish you the best of luck and hope everything goes in your favor!!! I can't wait to hear how your pref experience goes
