Blake is just really fake and rude, after he loses he is apparnetly a real piece of work in the locker rooms, I know lots of people who work at the tournament and they all say that. I've also seen him eating in the club restaurant and he is rude to the kids who come up and ask him for autographs. Once he was sitting with Mardy Fish and a few little boys came up to him and asked for their autographs, Fish was really nice to them and asking them questions, but Blake was totally disinterested. It was pretty low.
You are so right that people's personalities make them much more attractive, that's how my friend was with Nadal, she had never been really that into him but she said he was shy but also just so nice and accomodating, he really looks out for people around him. Plus apparently he is really tan and his being Spanish and so strong makes him more attractive, like he'll come sweep you off your feet

If he was American, he couldn't pull it off lol

I'd love to meet Federer, I can picture him being more attractive in person and being really interesting. I'd also love to meet Henman, someone I know met him and said he was really nice.
P.S. Where are you from in CO? I used to spend my summers in Aspen, I love Colorado!!
