What are bumpers?
She sounds like she loves her bowling?
They're metal railings that can be raised in the gutters of the bowling lane. They keep inexperienced or handicapped bowler's balls from going in the gutter and getting no pins down for that frame.
She simply adores bowling with a particular man. Danny is shorter than the PR, weighs about 300 pounds, is mostly non-verbal and has limited physical ability to throw a ball. He usually approaches the alley and drops the ball. I think his usual speed is about 1.5 to 2 mph according to the display. She simply loves Danny, it's not that she can beat him, she honestly likes him. And I'm glad.
