She knows to just smile & nod.
My favourite was when I heard some drunks giving Reyes a hard time and he shouldn't be a lead off batter (This was 2 years ago). I turned to my wife and said loudly, watch Reyes here he's going to get things started with a shot to right center for a double (He was on fire that week), just watch. BOOM, it f***ing happened and then everyone around me turned and looked at me like God.
