it seems to be about a girl who is in a bad relationship - although the guy makes her laugh, he makes her cry, too, and there is "no pleasing" him. she got into the relationship suddenly - "in one day you've made your mind up that someone is right enough for girl" - and didn't notice or ignored his flaws. her friends are trying to tell her that he isn't a good guy, but she won't listen. then at the end, the friends get sick of trying to tell her what to do when she never listens - "someday we write it off, we know it when we're ready and had enough."
