April Fool's Day is traditionally a day to play jokes on others. I
had such an experience to be fooled.
It was April Fool’s Day yesterday, but I didn’t realized. When school was over, my friend Jack asked me to have lunch with him in a restaurant. I agreed and told him to go there first and I would make my mother a call. By the time I got to the restaurant from the telephone box, I found he wasn’t there. Ten minutes later I realized I had been fooled. But I didn’t feel angry. When I went home for lunch, my mother had a good laugh.
