Dear Lucy:
Yesterday, I went shopping with Mary in the morning. The supermarket started at nine o’clock. We got up at half past eight and went to the supermarket by bus. We needed food for Wendy’s birthday. My father made a shopping list for us. We bought a big birthday cake and some fruit. We bought a dress for Wendy too. We didn’t buy any sweets, because they are bad for our teeth. After lunch, we walked to the park at three o ‘clock. We took photos in the park. And we went home at six o’clock in the afternoon. We were very tired, but very happy!
Love,
Billy
