I remember many years ago I used to drive down to Devon for holidays. Initially I'd see how often other cars would give way to me on the narrow twisting country roads. It didn't take very long for me to realise that it was far more relaxing and friendly to give way as often as possible with friendly waves and smiles.
I suspect boating on the broads is the same. Newbies comer along and try to use their "rights of way" wherever they can (whilst pushing their luck a bit with sailies, but after a while learning to relax.
I have been boating in one form or another since I was ten, so can't really remember when I started "chilling out" on the water, but I do realise that this "chilling" doesn't come quickly or easily to someone who spends most of his life driving a car either aggressively or defensively, working for perhaps a less than easy going boss, and returning home to the domestic stresses to be found there.
Those of us who have boating experience, know and enjoy the pleasures of giving way, assisting others, and generally living life below the speed limits. Sometimes I think we need to have more patience for those still getting the hang of it.
