A woman recently told one of my housemates that she "only wanted to be friends," even though they had gone on only one date. I told him he ought to retort thus:
"What is this just friends? There is nothing higher than friendship, for friendship is the bond that joins together the very Persons of the Trinity! And in fact, because your views of friendship are so impoverished, you clearly have no idea of what friendship is. I therefore deem you unworthy of it!"
