I did go back to the sorority I got invited to, but unfortunately this turned out to be a sad day too because I wasn't invited back again. I was really upset this day so I probably didn't seem like a very enthusiastic PNM. I wish I could go back and do it again. On the other hand, I saw one of the sisters who talked with me at that sorority later this semester and the first thing she said to me was, "Hey! I interviewed you at [sorority]! You were really great."
So I guess that's a start.
