Perhaps you are right. But possibly she doesn't quite know what she is looking for. From the outside, she may see college sorority membership as a chance for sisterhood and tradition, and she might not have considered the discomfort that might come from trying to socialize with 19-20 year olds. If she wants sisterhood and tradition with social events and service opportunities (exactly how many people define sorority membership), she might find it in places like Beta Sigma Phi or some of the other organizations and activities already mentioned in this thread. Since we are getting the story from a secondary source, we can't begin to understand what the woman in question really wants out of sorority membership.
With all due respect, I think my comment falls more into the "keep an open mind" file than the "She can always AI" bin.
