Here I’d like to share something about my best friend Helen with you. Helen and I are similar in many ways. She is as hard-working as me. And we both enjoy reading novels and playing the flute in our spare time. Although Helen and I have much in common, we still have some differences. Helen is more outgoing and thoughtful than anyone else I know. She always makes me laugh and helps me see the silver lining when I’m in trouble. Besides, she is so warm-hearted that she is always ready to help others by lending a hand. That’s why she has more friends.
