Ordinarily they were good at talking through disagreements, but this time they'd stumbled upon a snag. It wasn't that they didn't have anything to say, but what they had to say wasn't being communicated well. It was even getting hard to identify when the argument was under discussion and when it wasn't: It seemed to pop up out of nowhere, masquerade in different costumes, leave off only to pick up unbidden.
