Friends are a part of our lives. In my life，I have a best friend named Lucy. She means a lot to me. My life would be less colorful without her. Although we sometimes argue，we still treat each other as best friends.
We met each other four years ago. She said hello to me with a sweet smile. I guessed that she was a gentle girl. And she really was. When I was in trouble，she always stood by me and made me feel better.
This winter holiday，we went to the amusement park Happy Valley together. We had fun together on the roller coaster （过山车）. We held each other's hands and shouted loudly when we were riding the roller coaster. It was so exciting. The ride made me feel a little sick, so she bought a bottle of water for me. This experience left me with a lot of good memories（回忆） and made our friendship stronger.
There is a line in the movie Soulmate that says， "If you step on someone's shadow，you will never leave each other. " So I will try my best to "step on her shadow". Many adults think that children can't be friends forever. But I don't believe this.
Maybe we won't always spend all of our time together. But I will enjoy the time I spend with her and the good memories she has given me.
