Who can guarantee which one is scarier?

Someone once told me 'Everyone loves differently'. And it made me think why should the way in which someone fears be any different. Then I realized, it's not. You're afraid of the dark. For you a monster is a creature with creepy yellow eyes and huge claws that will scratch your feet as soon as you put them outside the blanket. I, on the other hand, am afraid of falling in love with someone who won't love me as much. Whose love will eventually fade away. For me the charm in your brown eyes is a monster. But who's to say which one is scarier and more dangerous?
