How come some people can get your heart pumping and others...eh, nothing? Like I might think one person is cute and feel nothing, but i might think another person is cute and be headover heels for them. And its not just in person, like whenever I see my celebrity crush I've had since I was 12 I STILL feel butterflies in my stomach. But then if I see another celebrity who I think is cute too, I don't. So yeah. what's the deal with this?
