Usually with your Big Sis it's mutually decided. Our pledges write down their top three picks for Big's, and the actives do the same for us to choose their littles. (It's almost like rush since rush is a mutual decision.) As for your Big Bro YOU decide that, and your Big Sis really has no say in it. I chose my Big Bro totally on my own. I think it would work out in your favor. I love my Big Bro, and I feel honored to be apart of his fraternity.

If the angels up above
Could hear us sing our song to you
They'd see that in our hearts
We're Pi Phi's from the start
