My sophomore year was my 1st year as an RA and also the year I went through formal rush. I had some of my residents go through it w/ me (they were all 1st years) and by the end of the year (since we had informal every term) about 8 of the 18 girls on that floor had gone PiPhi, it was insane! My Junior year I only had one resident rush (she's a PiPhi now too

) but the girls were very respectful and I never felt in my two years as an RA that there was any animosity directed towards me because of my greek affiliation, then again, ALL the girls who went greek on my floors went PiPhi
