     Everyone may play a joke on^① others on April Fool's Day^②. And my father did last April Fool's Day.

     It was Sunday and we were all sitting at the table when father suddenly smiled and said to us, "Oh, dear,

I forgot to tell you the good news. There's a letter from granny. She is coming to see us this afternoon. I'm

going to meet her at the station^③." With these words^④ he went out.

     How happy we were! We hadn't seen granny for nearly a year and we missed her very much. After lunch

my mother and I went shopping. We bought a lot of food that granny liked. My sister cleaned the house. It

was four o'clock when we finished and we sat around the table, waiting for granny. At last the door opened

and came in my father, alone.

     "Where's granny?" We asked.

     Father laughed and said, "April Fools! Today is April 1st, April Fool's Day."

     We were disappointed after we heard this, but we all laughed.
