I still remember his embarrassing awkwardness when he showed up at George H.W. Bush's funeral. All the former presidents and First Ladies were sitting together talking quietly before the service and George W. came over to greet them. Then TFG arrived along with Melania. She sat with the others who made room for her - but TFG failed to sit down, just kept pacing around as if he'd never been in a church before.

His father sounds like a sociopath too.
His mother was sick most of the time.
An older sister took care of the children.

As a young man Trump hung around with the cocaine and Epstein crowd.

Turns out he told her he didn't care. Apparently he was only looking for a son to bring into his business. His eldest and namesake, Mary's father, didn't work out - he had friends and ambitions and became a commercial pilot at the start of the jet age. However, his father disapproved, called him "a bus driver in the sky." And he eventually died of alcoholism. But his younger brother Donald worked out well, his father made him vice president of his company, paying him accordingly, while others did the actual work.

And after his father died, Donald tried to disinherit his remaining siblings - until his mother found out. But he was still so desperate for money since any business he started failed badly, so he eventually sold his father's lucrative company at a loss. I'm getting this from Mary Trump's book.

There is no bottom to his depravity and I’m shocked that I’m still shocked at some of his antics
