Technically Incorrect: It takes just nine hours for the president-elect to completely alter his Twittering views about protests against him.
Technically Incorrect offers a slightly twisted take on the tech that's taken over our lives.
The notion of sleeping on something before you act on it has helped many make better decisions.
A second-best option is to sleep on whatever you've said or done and try to redress it the next day.
This latter path was trodden by President-elect Donald Trump, just nine hours after this Thursday night tweet: "Just had a very open and successful presidential election," he tweeted. "Now professional protesters, incited by the media, are protesting. Very unfair!"
On Friday morning, he offered a slightly more positive tone. He tweeted: "Love the fact that the small groups of protesters last night have passion for our great country. We will all come together and be proud!"
Yes, there was a little dig about the protests being small, but this at least held out the idea that he wanted to embrace rather than strafe.
The bigger question, however, is whether this Twitter turn is a precursor to how Trump will rule.
Given that during the campaign he seemed to adopt diametrically opposed stances from one day to the next, will he rule that way too?
Will he decide to nominate a radically conservative judge to the Supreme Court before waking up the next morning and thinking: "Nah. I'm in a liberal mood today"?
Will he, indeed, feel entirely free to work with both sides of Congress on whatever issue is grabbing him by the, um, possibilities?
Those of fearful disposition will worry, of course, that President Trump will shoot off a nuclear weapon, wake up in the morning and muse: "No, I didn't mean South Korea, I meant North Korea."
So far, though, his Twitter account has revealed a lot about his inner psychology. There's a certain sensitivity there, especially with respect to how he's seen by others.
Like that Twitter account, the next four years are unlikely to be dull. Unless, of course, he wakes up one morning and tweets: "I've had enough of this president thing. I'm off to play golf."
