carnation, I totally agree with you about #2 and part of #1, but not ALL of it.
I totally agree that there are fabulous women who end up bidless in recruitment, especially at schools like mine... although frequently these bidless women choose to go bidless because they will not give houses that are not "top tier" a try. However, the women who thought they were "supposed" to be in A, B, or C who end up in X, Y, or Z often end up being devoted members of those orgs and can never imagine having gone X, Y, or Z. I can think of multiple girls from my sister's group of friends who went into recruitment hoping to pledge certain houses, got cut, and ended up happy in the houses they pledged, thus "the houses they were supposed to be in."
I guess it all comes down to whether you believe in sorority recruitment predestination or not?
Myth #3: Girls go into recruitment open-minded.
Even if a girl knows nothing about the houses going in, she is going to hear tent/bus/sidewalk talk about the houses. Even if she doesn't pay attention to that, she's still going to be able to figure out, to some extent, which houses fit into which groups. Being open-minded at the start will not stop this from happening, and if things like "old row" and "top tier" matter to a girl, she's going to take note of these things whether or not she has an open mind on day one of round one. It's nice to think that a girl will give every house an even shot, but I cannot name for you one girl from my own rho chi group or from any of my rec-writing experience who gave EVERY house a chance.
