When I rushed, I remember having 5 or 6 girls rush me at once at the chapter at which I was a legacy. To me, this was so bizarre, since at the other houses, it was more one on one. I totally panicked--how did these girls know so much about me? Why were they talking to me? WHAT IS GOING ON??? I knew nothing about rush, and when our group left, everyone came up to me and said they noticed that I had a ton of girls around me. Another PNM in my group then said, "Well, they're the most popular girls on campus. You won't get in." !!!
(I didn't get a bid there. But this gal got cut from every house after that round.)
My point is that rush is totally confusing and people say stupid things and you really have no clue what really goes on--and karma catches up to people. I think these girls genuinely were trying to get to know me, and I'm sure it was the same with your daughter.
