Oh please. She sees Roger once a year during the US Open. She probably spends more time with Mirka than Roger as she's sitting in the players box during his matches.
And she is extremely influential in many areas.
Roger (and Mirka) are very lucky to have caught her eye. IMO
She's a great person to have in your corner.
I feel that Roger knows this, too.
I think he enjoys going to these things mainly for Mirka's sake.
Love makes you do a lot of things you might not do otherwise.
