The person I liked when I was young was like a thorn. If they are together, they will take root and grow into a tree called home. If unfortunately they are separated, this thorn will always be a thorn in the heart. It hurts but can never be removed. Why would you be interested in a place you know nothing about? Why would you be so interested in a place you know nothing about and have never been to that you can clearly imprint its entire transportation map in your mind? Why would you be so repulsive to a place, so repulsive that you wouldn't even want to pass by it? All the answers lie in one person and a memory about this person.
