AIs: "First meeting, now what?"

My views are that why would someone WANT to join after college? I mean the sisterly bonds start early in college and the AIs won't feel the same bonds since they didn't pledge while a collegeiate. They won't have the same memories nor will they truly feel the same strength of sisters because as a collegiate one leans on their sisters much more so than an AI would. We have much more stress than an AI. They have never paid $330 per semester out of pocket. With us, alumnaes pay $10 per year whereas collegiates pay $660. To me it's a little unbalanced especially with dues.
