The media needs stories and they have no conscience. This is only the biggest story of the year when it comes to celebrities. I mean, that guy was the poster child for clean living and role models. A few tantrums on the course, sure, but the first athlete to make $1 billion, the most popular guy on the planet of his age... man, this is the trifecta - people, in general, love to see a train wreck, and this is a titanic sized personal catastrophe. He really hasn't had any dings, so now they finally have something, the whole house of cards is going to come down.
As for apologizing, they all have to apologize because what they are doing is morally wrong in our society. Thus, it's a marketing angle to look remorse and apologize for their transgressions. I believe Polanski had to leave the country or be indited (I think). Not saying Tiger isn't remorseful, it would appear that he's serious about making an effort to repair the marriage.
What's foolish, and you'll never change this, is a young man with as much fame and money as he (and so many actors, etc. have) and they believe themselves mature enough to settle down in a marriage. They just have no clue of the requirements and responsibilities. Hell, it's hard enough for the average guy, let alone somebody jet-setting around the world with women begging to lay him on a weekly if not nightly basis (and we're not talking about beer goggle women either).
I agree 100% with the deplorable nature of our wealthy class - it's just like the Roman empire's wealthiest citizens - normal becomes boring because there is no excitement, thus they dig into the depths of depravity. While Tiger's behavior isn't depraved, he took a vow, he said the words and he broke them. I can't help but think to myself two things:
1) He must not have been a man if he allowed his father to push him into a marriage he didn't want
2) At what point do you, as the world's most recognized *married* face, not think that screwing other women will not come back to haunt you?
On one hand, I'd like to see him resolve this, but on the other, I'd like to see her take him for all of it, take the kid and leave him with nothing but the desire to go play golf again.
