The way Dolores set up the pins was nothing short of hypnotic.
In particular, Barry admired the way she would grab the pin so firmly, just where the bulbous end tapered into a tubular shape. And then, how she so slowly slid her hand up the shaft, while the whole time shifting the pin to the perpendicular, until she let it wobble on its fat end, her delicate fingers just barely touching the slight swelling at the end of the pin.
Yep, Barry liked that. It made him want to sing.
Then he saw what how she polished the balls.
