Anywhere. Probably a hand-me-down from my parents. My dad was raised almost right on campus at the University of Missouri (a very different place then from now) where his dad was a physics professor. He saw frat life as it was then and didn't want any, thank you very much. The only one he was ever part of was Phi Beta Kappa. My mother, a kid from southwest Missouri, wasn't exactly a hick. Both her parents were educated, and she had two much older siblings with good educations. She just didn't have time for Greek life. Her aunt, a surgeon, had no children and paid for books and tuition for all her nieces and nephews, but there were a lot of them, so mom had to work for her room and board. She was, however, an excellent student, so she wasn't terribly surprised when some girls from Alpha Chi Omega approached her in the fall of her junior year, wanting her to become one of their happy number. She knew they wanted her mostly to raise their GPA and she wasn't interested. Besides, she had a nice boyfriend who wasn't a Greek, so thanks for asking, but no thank you. She also graduated Phi Beta Kappa.
When I was applying to colleges, my parents told me that if I wanted to be in a sorority, pledge dues and all that would have to come out of my own money. I never had the slightest inclination towards being part of any such outfit anyway. I had a few close female friends, but honestly had never cared much for women in groups. Still don't. And being a faculty brat and around campus a lot, I'd already seen enough of the behavior of the Freddy Frats and Sorority Sallys. The whole culture turned me off. Still does.
