Has Donald Trump ever laughed in his life?
Think about it. When have you ever seen or heard Trump laugh?
Find me a video of Trump actually laughing. You won't be able to , because he can't laugh.
He has no sense of humour. That's why they make fun of candidates he runs against, for simply laughing, because it is impossible to find Trump on tape ever in his life laughing.
He smiles for his Presidential Portrait, because he has to. However, he absolutely has never laughed, as far as I know, in his entire life. I think he only smiles for his portrait because they force him to, and if he had it his way, he would have his miserable angry look like Hitler, his idol, did for his photos.
