What To Do?

Needless to say, I am stressed to the max right now while I am trying to finish my Master's Thesis that is due in a week and two days, and am just about as wound as tight as one could be wound. But i just found out some things an hour ago that could get someone fired and in some legal trouble if the information got out. I'm keeping my nose clean and am keeping my mouth shut about it just because I sure do not need any more drama in my life right now. I just hope and pray that the person involved will have a moral and ethical epiphany and do the right thing.
