The other side of rush is much better than going through as a PNM, in my opinion!!
At my school, we had to sit out in front of the houses, and in Central Florida, August is HOT and HUMID! Not only is it hot, but we had to sing these songs over and over and over, until the sorority would let us in the house. It gets old!! Really fast!!
Don't be nervous about being on the other side. It's lots of hard work, but think about how nervous you were the year before. It's honestly a great bonding time for the sisters!!
