To me, my great grandmother, Muh, was the wisest woman in the world. She used to say this quote to me all the time which said, "A dog that will bring a bone will carry one back."

As I matured and got older, I realized what she had been trying to tell me for years, which was to simply be fully aware that the person sharing conversations and the personal business of others will in-turn go right back and share yours. So, moral of the story... starve the dog to death when the bone brought to you sows discard and/or promotes the dirty laundry of others.
