Did you know all these people personally? Did you talk to them personally before they left? Do you even know their names? If not I think you are just listening to and spreading dumb gossip that probably isn't even true and is exaggerated like when people say half the PNMs were dropped after first day or something. It isn't smart to believe and spread gossip. Try to concentrate on yourself and not what you think other people are doing and you will end up a lot happier.
