Rosie's a hypersensitive idiot. Andy would've merely blinked at her and she'd take it the wrong way and hate him for it. People like that are always looking for any little excuse to hate someone.
I was surprised, too, to hear that the Henman loss affected Andy so much. I wonder why? Henman's always caused him problems; it's not like he can steamroll over him. But you're right, we don't know the "real" Andy, we only know the Andy that he presents to the media.
And I'm dying to know what went on after Andy lost to Pim-Pim at USO. To me, that was his most inexcusable loss of the year and I hope he was thoroughly disgusted with himself.
Ah, to be a fly on the wall.
