In our chapter, each of the final three weeks leading up to initiation we would be paired with a Delta sister that we might not know as well in order to get to know them a little better....what we called Violet, Lion, and Pi Sisters.

We received our diamond sisters within a week of receiving our bids, so we also had that special relationship developing, but I think this was a way to make sure our relationships didn't become too exclusive (only to our diamond sisters or fellow Alpha members).
