A Little Epiphany - (and a newbie delurking)

[Dia]

perseverate - to focus intently, even obsessively, on something - usually to the exclusion of all else. Comes from the word 'persevere'.

Not silly, it's an unusual word and I'm surprised he used it. You only typically hear it in one of two contexts: about autistics or in a clinical/counseling setting related to something like OCD.

To be clear, I think he does perseverate, just not abnormally so.
