I stay out of others' business as much as possible and try to be frank with people. Edgar Allen Poe wrote about the imp of the perverse in each of us that makes us want to take part, at least out of curiosity, in the misfortune of others. While I don't think it is necessarily a grievous sin I do think there are better motives to get involved if one does get involved.

Maybe it's the reality tv influence that has made us more willing to become spectators anonymously enjoying the pain of others.
