I've known some players to tell lies about other members to cover their own tracks as well. Blatant untruths about others, about how they have been treated, and other more nefarious things in order to cover their tracks. It has cause no end of trouble, and hurt.
Playing with anyone's emotions, or feelings, is in my humble opinion just wrong. But, I'm a caveman ..
Yesterday is but a dream, tomorrow only a vision. Today, well lived, makes every yesterday a dream of happiness, and every tomorrow a vision of hope.
