Been on my mind a bit, this topic.
I've seen quite a few threads on MN where someone has done something apparently helpful for the OP, yet the OP feels irritated and/or undermined.
People then queue up to beat the OP around the head and shout at her that this helpful person is lovely, how DARE she be ungrateful and she should consider herself lucky because other people's friends and relatives never do anything for them/beat them to death every night with a stick/eat their children/whatever.
I think this is naive actually. There are some very controlling people around, and for someone like that (I've known a few) one of the most satisfying ways of controlling someone else's life is to help them - whether they need help or not.
I would say that if an offer of help has been clearly and firmly declined, yet the "helper" forges ahead regardless, then they're doing it for their own gratification and the "helped" person has every right to feel miffed and vent angrily on MN.
Or AIBU and also a nasty cynic?
