One afternoon, when I was on my way home, the sky 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 I was hurrying home , I heard of someone calling me from behind . I turned to have a look and find that he was Liu Wei , a good neighbour of me . He offered to share his umbrella with me . We walked all the ways home . Without Liu Wei’s help , I would have got wet to the skin . How much thankful I was for his help !
