IU PNM, I'm really sorry to hear about your situation. You seem to have handled yourself very well and kept an open mind; I'm sorry things didn't work out for you.
Apparently, this year there are so many girls at preference round that there are 4 rounds of parties except for 3. PNMs can still only attend up to 3 parties this round, but some houses have invited more girls back than they can accommodate in only 3 parties.
I have no idea if this has happened in the past, but if this is the first year, I guess it's really showing the sheer volume of girls going through recruitment at IU. For some that I know, recruitment has been absolutely fabulous so far and they've continuously received invites back to their favorite houses. But for many others, myself included, it's been lots of brutal cuts. Many girls have dropped out and a girl I was talking to yesterday said that her rho gamma told their group that over 50% of PNMs attending 8 party had 3 or less houses back.
I have 2 houses for preference round, one of which I really like, so I guess I can consider myself pretty lucky. I'm actually about to leave for my first party right now. I hope all goes well and I wish any other PNM at IU good luck.
