Maybe I misinterpreted your question. My answer was to a question more along the lines of "why do parents talk about parenting all the time?" If the person offering advice is being a dick about it (be it about parenting or anything else), then sure, it's inappropriate. But at the same time I remember when my first was born, I was pretty darn receptive to advice because _I had no idea what I was doing_. I'm less receptive now because half a decade in I think I have a decent handle on things, but I'm still not hostile about it -- I generally smile and nod and ignore (which, come to think of it, is what I do whenever anyone offers me advice I don't need).
