Theory about talking to myself

A theory about why when talking to myself, I will say such senseless phrases as the one I just now said “no refunds or credit”: that these are the random words that happen to be passing through my brain at the same time as I have an uncomfortable thought.

So if, for example, I happen to think that phrase “no refunds or credit” at the moment I recollect there’s an important test I have to take tomorrow, I will repeat that phrase aloud as if it were a weighty utterance, which somewhat staves off the uncomfortable thought. “No refunds… no credit.”
