If you do feel that pledging is not for you that is O.K.  Pledging is not for everyone, just make sure that it is the decision that you want.  The connections that you make with the sisters as well as the pledges will stay with you even when you drop.  If you are not ready to pledge for the whole six weeks you always have the option of pledging next semester.  Just to let you know that when pay your dues for pledging you do not get that money back.
