My parents were very much against my joining a sorority in college--culturally and philosophically they did not agree with the Greek System. They did not understand why I would want to pay to join a social group, and they felt it was all frivolous. I went ahead and did it anyway. I got a job to pay for my dues. They still kept up the negativity (my grades, my focus, my career-fraternity parties are bad, what was I doing...blahblahblah) but I knew from day 1 it was the right decision. Those women turned out to be the best friends I ever made.
My mother finally came around about 3 years after I graduated. She threw on my old sweatshirt w/ letters one day and wore it to the grocery store). An alum happened to see her and starting raving--are you an alum-where was your daughter a member---is she ever in town..." It turned out I was in the process of moving to their town and this alum introduced me into their chapter a few months later. My mother started singing a different song after that. She said, "That XYZ. It's not a bad group, you know.
I'm glad you joined."
