You have simple men with grandiose delusions and they are granted a type of control/dominance over the lives of others. They are not trained professionals, they are typically well-meaning deluded souls with an illusion about themselves. Because they are not trained professionals, they have little to no concept of the damage that can be done by sharing private information with others, no matter how close and how perceived trustworthy.
Then, factor in the drama. They all love a good soap opera, so when it unfolds, they can't wait to "share" because he who knows most or knows first for some unwritten rule claims a superior spot. So....the babbling begins and it surely does travel.
Gossip is one of the hugest issues these people face - and it is borne of boredom plus that organizational fostering of superiority of one over another. All in all, pretty stupid and I'd say childish, but kids are more just plain mean up front and get it done and over with and move on.
