It's not a contradiction at all - people can at some moments control themselves and at others they can't, and can switch between them very quickly. I've been to funerals where I can hold myself together and then a stray thought or something just completely sets me off and I get very upset.
As for taking responsibility - yes perhaps he could or should have said something in reference to his distress, I don't know. I'm pretty reluctant to tell people how they should feel or how they should show it - while displays of raw emotion can be uncomfortable it doesn't necessarily make it wrong either. What I think was the problem here is that it did end up taking the focus away from Rafa, and I think it is still doing so. Rafa did an amazing thing to win the Australian, winning two five set matches back to back in the last two rounds, playing nearly 10 hours in those two matches with 1 day of rest between, and to a degree I think Roger's reaction has taken too much focus away from that. That's where I'm coming from in all this - that it should really all be about Rafa's win, not Roger's loss.
Nice piece of verbal gimnastics there.... oh, well... doesn't matter, as MTK said, is all matter of opinion. Perhaps the only thing we really differ here is the tone, or basically the harshness-level of critique. Fed can cry all he whats as far as Im concerned, not the first time Ive seen him do it. Just that this one I found really bad since even now that he lost he managed to ruin it somehow and make it all about himself again. Nothing new though one can really wonder whats gonna happen next time he loses GS finals to Nadal. Cheers.
