Speaking of being naive, when I went through Rush as a freshman, I looked through the Greek View Book and decided immediately that I wanted to be an Alpha Delta Pi because it had three Greek letters and the other sororities on campus (Phi Mu and Delta Zeta) only had two!
Of course, after the first couple of rounds I realized that my original idea was completely irrational. Thank goodness - because I would have missed out on all of my wonderful DZ experiences! Funny thing was that I spoke to one of my pledge sisters last year (7 years after our Rush) and she told me that she had originally decided she was going ADPi for the exact same reason! haha
