    I stared at the word "Happiness", my creative-writing assignment (作业) about emotion, on my blank(空白的) paper. No format(格式) at all.

    It was not the lack of structure (结构） 1the word "happiness" that was 2 me. Anything else I could have 3 well, say, jealousy (嫉妒) or pain. But I was 4 to write about happiness.

Maybe butterflies aren't exactly the 19 to happiness, but there is something to be said about the simple things in 20. And with that, I started to write.
