When my son, Justin, was four, he found a caterpillar (毛蟲) and put it in a jar. Each day he fed it with fresh grass and leaves. In a few weeks we discovered it 　36　 in a cocoon (繭).

Justin was excited. He knew a moth (蛾) or butterfly was about to be 　37　, but he didn’t know what kind. He was　 38　 to know what gift nature was about to give him.

“Dad!” shouted the boy while running to me one day. “Something’s 　39　. Come see!”

He led me to his room. The cocoon had become half transparent and we could 　40　 the wings of the unborn. Soon, a moth broke free from the cocoon, and laid eggs completing the life 　41　 of the little caterpillar.

The next day, I convinced Justin it was time to set the moth free. He took it 　42 , opened the jar, and the little moth flew out. It 　43　 the yard twice, came back, and landed on Justin’s arm. He picked it up, tossed it in the air, and the moth repeated its　 44　 pattern. He tried over and over, but each time it would 　45　 to his arm.

Justin　 46 _. He put his little pet back to the jar. The next day he attempted to set it free again, and after a few repetitions of the same behavior, the moth　 47　 flew off into the grass.

Like a 　48　, I believe the moth was afraid to leave what it was comfortable with. It wanted to stay with something　 49　, scared to move on and experience something unknown.

I was once that little moth. My cocoon was my mother’s 　50 , in which I was comfortable. Like the moth, I didn’t want to fly too far away from it. I was　 51　 when my first job required me to move to a new city. What would I find there? I liked　 52　 I was.

Humans are creatures of 　53　. We resist change. However, if I hadn’t moved, I would not have experienced many　 54　 and wonderful things or met many of my friends. So each move gave me the 　55　 to learn and experience, but best of all, I met friends.
