I think while real, a huge percentage of posters air their concerns / problems and want to hear everything will be ok but not take advice or change things at their end.
Frustrating sometimes for those who reply thoughtfully but are batted back with OPs just continuing to ask the question they want to hear yes to until someone gives them the "right" answer even if it's 99/100 posts saying the opposite.
But they don't owe us anything so I guess it's silly of me to feel frustrated!
