I also asked my boyfriend's sister to write me a letter to her sorority, Ash. Although she thought I would fit better in a few other houses, she wrote me a very nice and complete recommendation.
Wait, what? Was she an alum of the chapter at your school? If not, how is it her place to say that unless she refused to write you a rec?
Yes she is a young alum of the chapter. It's not that she didn't want me to be a part of her chapter, she just thought I would personally like other chapters better. Sorry for the confusion!
