Is it possible that this guy was making a clueless and clumsy attempt to flirt with you? This thread brings back memories of similarly clueless men when I was young and single. Some men just didn't get it that women's humour is different than mens and we generally don't do the sort of banter that they do between themselves. They'll make insulting remarks in what they think is a joking manner and are puzzled when we don't find it appealing or funny.
