If people don't want to listen, you will only place yourself in the firing line by continuing to interfere. Both for interfering, and as someone "involved" when it invariably goes south.
When I say only, that is incorrect. There is also the added bonus of wearing out your welcome with those who reluctantly waste their time offering advice to the middle-man in a game of chinese whispers to provide advice that, regardless of how effective the canny middleman is, is not wanted by the person who ought to be taking it.
The same applies when a doting grandfather seeks vicarious advice, with half of the story, and none of the facts, on behalf of a grandchild who CBA to do anything themselves.
This is intended more as a salutary tale on the perils of vicarious advice than as a dig at a well-meaning poster whose skin is far too thick to be affected by such comments.
