Last March, my mother told my father and me that my grandfather would come in April. We were very happy because my grandfather was an interesting old man and he had not visited us since he went to Hong Kong.  On April 1 my father and I bought a lot of food from the supermarket and bought a big bunch of flowers home. Then we did some cleaning at home. At night when we were waiting for my grandfather, the bell rang and in came my mother. She smiled to us and said "April fools"!
