Well… true confessions, sometimes, given my background, I do occasionally offer unsolicited advice. 
It’s second nature to want to help “fix” a problem. Have to sometimes stay silent when they may just be venting. That said, frequently they are actually asking for a suggestion. Just yesterday the HVAC guy asked if I was “psychoanalyzing him”. My usual response is “the meter is not running”.
Many years ago I had to call an attorney to clarify if he represented the son or the father. The father was clearly being taken advantage of by the son, but the dad was just in the process of being evaluated and hadn’t yet been declared incompetent. I’ll never forget the attorney’s response, when he said he represented the dad and was aware the son was taking advantage of the dad, but the dad had not yet been declared incompetent, so was able to make bad decisions with his funds (and his yacht). His response was “the law protects those who cannot protect themselves. It does not protect darned fools”.
