You know how it is, right, ladies? You know a guy for a while. You hang out with him. You do fun things with him—play video games, watch movies, go hiking, go to concerts. You invite him to your parties. You listen to his problems. You do all this because you think he wants to be your friend.
This, by the way, is why I have a problem with those breast cancer campaigns whose message is “save the ta-tas.” It implies that a woman’s breasts are more important than, y’know, *the woman*. (It also erases male breast cancer patients.)
