Happiness depends upon ourselves

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）______ the word “happiness” that was ______ me. Anything else I could have ______ well, say, jealousy (嫉妒) or pain. But I was ______to write about happiness.

There was a ______ at my bedroom door. “Hey, Sarah?” asked a small voice. “Can I come in?” “Rachie.” I said to my five-year-old sister. “I’m ______ now.”

“But this is important.”

I ______. “Okay, then.” Rachie came in. “Um, I caught my favourite butterfly. It’s ______ pretty. But I let it go because Mommy said it would die.” “So, what’s the ______?” I asked. “Well,” she whispered ______ she were about to share a deep ______. “When I set it free, I was ______. Does that make me a mean person?” I ______. “Of course not. You were just happy it was free.” I gave her a ______ . “Now I have work to do.” “What work?” she asked. I ______ my blank paper. “I have to write about happiness.” “Oh, that’s easy.” “What’s your happiness?” I asked. She thought a few seconds. “Butterflies,” she said ______ and left.

Butterflies! I thought about our ______. She was happy to catch the butterfly and happy to see it go. Maybe she was right. Butterflies ______ nothing but happiness.
