We had formal, ritual chapter once a month, and the rest of the time it was informal. Our chapter always had a ritual practice before a NO came in because they didn't only quiz us on ritual chapter meetings, but also intitiation. The older sisters knew it because they have done it so often, but the younger girls weren't as secure in it. If we didn't securely know it, everyone had the gist of it, at least. I hope everything goes well with your friend's chapter!
BlueViolet: Yeah, we had a few of those "OMG!" moments....like we were singing a ritual song to the completely wrong tune.
