what does this mean

I'm not looking for you guys to tell me what house I should choose or anything, but I'm preffing Alpha Chi Omega, Alpha Phi, and Pi Beta Phi. I love all of these houses, but when I was talking to my Rho Chi about choosing and how I felt about these houses, she just said "wow well that's an interesting combination" and the way she said it just kind of bothered me. Does anyone know what this means or why she would say something like that? She kind of made me feel like I'm inferior in some way because of the houses I chose? Any input would be appreciated.
