It was a wonderful spring day.The Earth was finally awakening from her winter sleep.New life was everywhere.The sky was clear and blue.The air smelled sweet.The sun was kissing the world with its warmth.It was already nearly 21℃.
I was driving to pick my son up from the workshop,where he works a few days a week.On my drive I saw various beautiful flowers in people’s yards.The fields were full of yellow dandelions(蒲公英) with some already turning into little white balls of seeds.
The trees were starting to awaken too.The blossoms on them were white,purple and pink.The songs of the birds were in the air as well.I was taking it all in and feeling the love from the creation all around me.I longed to be a part of it and share my love as well.
I pulled into the driveway of the workshop and parked my car.As I got out,I saw a lost little butterfly larva(幼虫) moving the wrong way towards the sidewalk.It was just about to go under my tire when I reached down and picked it up.I held it gently in my hand and walked over to the grassy hillside on the other side of the parking lot.Before I put it down,I said,“You will never become a butterfly if you get run over,my friend.The best place you stay is the grass.”
Just then,it was time to leave work,and my son came out.As he saw me,he waved from the distance.I hurried to meet him,still holding the butterfly larva in my hand.When he saw what I had in my hand,he was very curious and asked me what I was holding.I told him and said I was going to put it back in the grass.
