Narrative:

Almost did a runway incursion. Was holding short of runway 7R/25L on B9 waiting to cross sbound to south ramp. I was flying. The aircraft's owner and his wife were chatting when I thought I heard ground clear us to cross runway 7R. As I released the brakes and started to power up to cross, another aircraft acknowledged the transmission. At that point I realized the clearance was not for me. Luckily I had not crossed the hold short line. I cannot emphasize [enough] how a sterile cockpit would have prevented this near incursion.
