Mr Jackson is seventy-seven, but he likes eating ice-creams. On his way home, he buys one. Great! No one sees him. He can eat it now. Suddenly, he sees Mrs Smith come here with her dog, Bill. Mr Jackson doesn’t want her to see him eating an ice-cream in the street. So he hides(藏) it behind his back, and says hello to her, and she talks a lot about her family. But Mr Jackson worries about(担心) his ice-cream very much, because the dog turns round him to lick(舔) it.
