Love tennis and used to play, occasionally wave a racket in the vague direction of a ball, but I can't run any more
Love football too - well the skilful stuff, not kick 'n rush.
I've played (at) golf - I am hopeless at it. Would rather play it than watch it though. I love sport, but not all sport. F1 drives me insane
I understand frustration at the game not going your way when you're used to it doing so, but you don't hit a ball flat out right at your opponent, like Federer just did.
