Homesickness is not always a vague, nostalgic, almost beautiful emotion, although that is somehow the way we always seem to picture it in our mind. It can be a terribly keen blade, not just a sickness in metaphor but in fact as well. It can change the way one looks at the world; the faces one sees in the street look not just indifferent but ugly... perhaps even malignant. Homesickness is a real sickness--the ache of the uprooted plant.
Stephen KingWhen the dawn was still long hours away, bad thoughts took on flesh and began to walk. In the middle of the night thoughts became zombies.
Stephen KingIf you can't laugh when things go bad--laugh and put on a little carnival--then you're either dead or wishing you were.
