Help grandpa cross the street and write 300 words.

Today, when I was walking at the crossroads, I saw an old man trying to cross the road, but there were so many cars on the road that it was difficult for him to cross. I quickly ran over and asked, "Grandpa, do you want it?"

Have you ever crossed the street? Grandpa said, "Yes". I said, "Grandpa, be careful. Let me help you cross the street. " I helped grandpa cross the street slowly. He said happily, "Thank you, good boy." I blushed and said, "You're welcome, this is what I should do." When I got home, my mother knew about it and praised me as a good boy! I am very happy today, because I did a good thing.
