No one has mentioned intentional mental hazing. It takes a toll on a chapter.
Initiated member(s), intentionally and continuously giving incorrect/unkind information to their own new members/pledges, can leave NM feeling left out, confused, unwanted. As examples:
Initiated Officer (I.O.) gives new members her incorrect phone number, stating she is "there for you always" but leaving a funny feeling in NM minds when they get the wrong person on the other end of the line (I.O. never does give out a corrected number).
I.O. tells NM to attend Derby Days at Lake Sunshine 2pm Saturday; in reality NM should have been at Sigma Chi parking lot for Derby Days @10am Saturday.
I.O. tells NM there are six beds opening for NM in the house Spring semester--deposit your rent checks now!--when in fact there are no such openings and the whole second floor of the house is being closed Spring semester for repairs to the roof/attic.
I.O., in a serious tone at a NM meeting, mentions someone in NM class is spreading rumors the Chapter President is a lesbian.
Due to this and many other unkind examples a NM class shrank by 40% over the course of a semester. COB the next semester brought a large class, with the same shrinkage result.
