The way I look at it from an advisor's standpoint is this: if I were a collegiate in this chapter, would I think it was weird that an advisor was there? We were all collegiates once, right? If I feel like I shouldn't be there, then it's probably best that I butt out. EC/Chapter/rituals/recruitment/philanthropy events are pretty much what I stick to
