I recently caught up with a hall mate from last year who took last semester off. In the excitement of seeing her again, I mentioned my best friend and I are living together off campus next semester and when she seemed interested, I told her she could live with us. But then I remembered a lot of her personality traits that clash with me and my roommate and realized I would much rather prefer living with just her. Is there any way I can kindly tell this to my old friend? I know that one way or another I will be being throwing her under the rug
