"‘I’m bored’ is a useless thing to say. I mean, you live in a great, big, vast world that you’ve seen none percent of. Even the inside of your own mind is endless. The fact that you’re alive is amazing, so you don’t get to say ‘I’m bored.’" -Louis CK via
If you want to know if someone is "real" tell them an obvious lie. A human will recognize it for what it is immediately, a cursed will not. They may look real, but they are not. Only real eyes realize real lies.
