I was always wondering the same thing, however i don't know my father and my mother never shown me any 'love' or 'affection' so i don't really know much about those. my grandma on the other hand was the one to help me, 'love' me and so on. i believe it was the same for my 2 brothers. My mother is kind towards me, however she treats me more like a very close friend, instead of daughter.

There are many types of monsters that scare me: Monsters who cause trouble without showing themselves, monsters who abduct children, monsters who devour dreams, monsters who suck blood... and then, monsters who tell nothing but lies. Lying monsters are a real nuisance: They are much more cunning than others. They pose as humans even though they have no understanding of the human heart; they eat even though they've never experienced hunger; they study even though they have no interest in academics; they seek friendship even though they do not know how to love. If I were to encounter such monsters, I would likely be eaten by them... because in truth, I am that monster.
