This is the way I respond to abusive people as well.
Don't sit there and take the abuse.
Don't get mad and lose your cool.
Just get up and leave.
Had a guy I never met before, we had just been introduced by a third party, cuss me like hell on the phone because of something he thought I did which never happened. He had no clue what he was talking about.
Didn't say a word.
Then, on the same call, he said that he wanted to meet me in person for lunch. HaHaHa LOL...
I told him not a chance in hell brother, click.
Although he pestered me for weeks afterwards to meet, nah. I never spoke to him again.
He thought he had established himself on the high ground as the dominant abuser.
That shit doesn't work with me. I don't play those power-play games. And apparently, neither does Trump.
