Like one poster already said: "when other people think they know your horse better then you do (and tell you what to do)". I have no problem what so ever when people offer help (any kind, say for loading the horse) though. I always appreciate that.
I also very much dislike snobbish horse people and those who think their discipline is the only way to go and everything else is a garbage.
