My sister married a Hell's Angel 35 years ago, he was a nice guy and everybody liked him, but after a year or two of marriage she started nagging him to "comb your hair, take a bath, stop looking like a scruff, stop your drinking, stop your smoking, stop your gambling, and stop going out with your mates so much".
But all he said was "I'm not going to change, why should I? You chose to marry me as I am".
He had a very good point, nobody forced her to marry him..

They eventually divorced after 17 years and he went straight out and married a nice woman who accepted him for what he was, but my sister hasn't had a man since then, nobody will go near her because she's such a nagger..
