Unhappy people

Have you ever met someone that you feel sorry for, because they seem like they aren't happy and don't want to be happy? One of my co-workers, the receptionist in particular has got to be one of the most unhappy, discontented people I know of. I no longer feel sorry for her, my sorrow has turned into rage (honestly). I found out today that she's been giving her personal opinion of my friendship with another co-worker. Basically she knows nothing about nothing, but insists of expressing her thoughts. This vexes me, because I am a direct person. I'd love to confront the situation, but for the fact that I don't want any drama at work or for her (the receptionist) to be angry with anyone else at work. At this point I've given up on her ever being a decent human being, I've come to the conclusion that she's a sad and pathetic case. And the sad apart about it all is that she's content and "happy" being in the position she's in --she's at peace with having no dignity or true friends. I guess I have to just suck it up and let it fly. Back to work tomorrow. All smiles.
