For your consideration ...
I just really hate that NY brash attitude, President or dog catcher doesn't matter.
It's not that he is brash. Trump has always said what he's meant and meant what he's said. But the majority of people have become so accustomed over their lives to hearing word salads and obfuscative speeches and talks, and non-answers to questions, when they hear Trump, many think he's arrogant or brash. People today just are not accustomed to hearing someone speak so candidly, as Trump does.
He's been a deal maker his entire life. Probably entering into thousands of contracts and agreements over his business life. In negotiations, (contracts, sales, buying, etc.), there is no room for BS. They are all serious matters. If someone is coming off being sly, seen to intentionally obfuscate their position during contract negotiations, it throws up a red flag, and most likely will not come to fruition.
And that is how Trump deals with everything, up front and a straight shooter. Some people can't grasp people speaking like him.
I've never been a Tweeter. Too busy with work to make time for tweeting. (That's for SGI....he'll choke on his breakfast donut when he sees it)
Difficulty multitasking? Me too. Only have time for forum postings.
