Let me make clear about usage: (1) up close and personal means i) to get to know very well about somebody or something or have a good knowledge about something, and can indicate ii) use of violence or sexual relationship depending on the situation due to its physical nearness implication the phrase conveys.his is a very plausible tone to take when using this expression, and it strongly implies violence. He tried to get up close and personal with me means something a lot like he got in my face.. It can also have a sexual connotation, again to me it has a subtext of bringing a long-building situation to a head.
Another term he used was emotionally closed. It means they don't like talking about the things that matter and they don't want to hear it from you, either. They'd rather talk about the weather, politics, sports, or anything that's not of a personal, intimate nature.
