Different sororities have different characteristics. That being said, there does seem to be one constant. Sorority girls flock together. Seeing a sorority girl without one of her sisters is a rare site indeed. It's also kind of creepy when a large group of sorority girls just starts singing spontatneously. No one girl starts it, they just all start instantly, apparently without any starting signal. I attended one sorority formal, and a fuse in the sound system blew out. Out of nowhere these girls just started singing one song after another, with no direction from any particular member at all. It was kind of weird.
