"too vicious...too nasty, too horrible," according to his wife

From an interview (Wash Post, 12/10/15) with D. Trump. In his own words....

I think I'm a very nice person who gets along very well with people. I'm very loyal, to a fault. My wife said, "You're too nice too long and then when you go bad, then you're too bad. You get too vicious and you never forgive. You put up with too much too long. You get screwed by somebody. You're too nice and then you flip, it's too long, too nasty, too horrible.
