Being a hopeless romantic means that you tend to see the best out of people and create imaginary situations. And that you get badly dissapointed with all those that ain't how you thought they were. And that you appreciate things that others can't seem to grasp. And that you let yourself suffer more than others.
I don't think that romantics have diminished recently, only they've made their cover better, like superheroes, and you can't distinguish them. But otherwise, people are misanthropes nowadays and get happy at others suffering. In any case, even though I think that my romanticism is a flaw, this is something I can't get.
