Do we believe him?

I Tivoed Tiger Woods today because I had to work (yes I have no life). I just watched his press conference and I am not sure how to feel (and why I care). I agree that the press needs to leave his wife and children alone. I also agree that his marital status is a private matter between he and his wife. I guess what I question is how sincere he really his. He apologized many (many) times but he seemed so cold and direct. I think in this situation actions will speak louder than words. We will see....
