I was just thinking this over and I've noticed on here that there's a few people (who will remain nameless as I'm not doing a personal attack!) who turn up on nearly every single parent/contact thread in AIBU and chat and tell the OP what to do. Usually whatever they say is completely in defence of the NRP (usually a man on these threads I've seen) despite a torrent of uncaring behaviour towards the children that the OP describes. These users have posted about their own situation before which is happily married and never been a LP. It irritates the shit out of me that they try and tell LPs what to do and how to put up with awful exes (and let them dictate everything because at least they are trying!) and attack them for trying to get maintanence their children deserve and need despite never having had to deal with that frustrating situation themselves. I kind of think if they had, they wouldn't be so aggressive with their defence of lazy NRPs.
So it got me wondering! Does that kind of advice from people who've never been there annoy you? How do you handle it in real life when someone who has no clue tries to give you advice on it?
