One afternoon after I was on my way home，the weather changed suddenly．Dark clouds were gathered．I began to feel worried because I didn’t have both a raincoat or umbrella about me．It soon started to rain. Just as 1 was hurrying home, I heard of someone calling me from behind．I turn to have a look and found that he
was Liu Wei, a good neighbor of mine．He offered to share his umbrella with me．We walked all the ways home．With Liu Wei’s help, I would have got wet to the skin．How thankful 1 was to his help!
