"I stand corrected Miss Paigey, and Terry, I'm not just ready to bowl, I'm ready to dominate." Bobby was competitive, but not nearly so much as he was pretending to be. He was doing it just to be fun and make it seem like it was some great contest. As driven as Paige could be to excel, he didn't assume that anyone could beat her at anything if she really put her mind to it. Mostly he was just playing with Kitty.
"Oh don't worry about your age, Kitty... I mean.. I hope I get around as well as you do when I'm your age." He was older than her, and she was still young, so he thought the absurdness of poking at her age was a safe enough thing to play with. He buckled and started the car. He set the heat to what he figured would be comfy for everyone else, and started off when everyone else was in and ready.
"I've got a Hamilton in my pocket that thinks I'm going to have the high game" The 10 dollar bill apparently hadn't seen him bowl before...
