[specialist]

I do this all the time. It's a form of rubber ducking.

Articulating myself, to myself, even if I don't share it, is often worthwhile. Why do I agree? Disagree? Is my observation novel? Enough to share?

Once I figure out what I'm thinking, do I care enough to share? Is the recipient worth my time? Do I really want to interrupt someone who's digging themselves into a hole?

Etc.
