Quote by J.K. Rowling
...as they slid stock words and phrases back and forth between them like beads on an abacus.

Summary
This quote describes a situation where two individuals are engaging in a conversation or argument, using pre-established and cliched expressions in a mechanical or unoriginal way. The comparison to beads on an abacus implies a repetitive and calculated exchange, lacking genuine thought or depth. The quote suggests that the individuals are not truly engaging with each other, but rather relying on well-worn phrases as a substitute for authentic communication.
