From the moment Donald Trump decided to run for the presidency of the United States, it was clear that he was going to be very different from any other candidate.
When he won the election he momentarily showed signs that he would follow protocol, but he soon reverted totype.
Clearly he is a man who does not like doing things the conventional way and this is almost certainly what got him elected. He rode into the White House on a wave of discontent with the state of America.
The majority did not vote for him - that honour went to his vanquished foe Hillary Clinton, who snared about 2.7 million more votes that Trump. However, he won the electoral college votes and that made him the 45th president.
Since the election, the president-elect has thrown out the rule book. A case in point is his friendly chat with Taiwanese President Tsai Ing-wen, upsetting China, which does not recognise Taiwan.
But it is his use of Twitter that has stirred the most interest. With about 16m followers, he has used this as a way of communicating directly with Americans.
However, it has revealed that he is still as sensitive as ever. The comedy show Saturday Night Live has regularly lampooned him, with Alec Baldwin doing a good impersonation of him. This has incensed him and caused him to rant on Twitter.
There have been other examples as well which suggest that his temperament is not quite presidential.
