What's happy? Is it smiling? Is it excitement? Maybe, it's satisfaction or maybe just a humour.
How long can happiness last? Why don't I seem to be able to keep mine? Perhaps, I often forget to stay happy, not only for miseries but also tiredness. Every luck I gain doesn't feed me for more than a week, vanishing at a steady speed that I don't notice it at all.
Does "not sad" mean happy? Doesn't happiness of others bring me happiness? How do I find my happiness? Does exhaustion kill happy? Does bringing inconvenience to others slay happy? Does lonesome repel happy? Does staying happy in bad times mean fooling myself?
