It was last summer.My wife Elsa,our little monkey Katy and I were driving home to Greenwich Village in New York City.We had visited our friends in Washington D.C..It would take us about four hours to get home.Katy was not happy because she had to stay in the car all the way.She jumped here and there,“Put her in the back seat and give her something to eat,” I said to Elsa.Just then she jumped on my right arm and immediately there was a big bang.Our car crashed into the car in front and caught fire.Fortunately,the police arrived very soon and they got us out of the car.“Oh,poor Katy is still in the car!” Elsa scrammed and ran back to the burning car before the policemen could stop her.She opened the door but found Katy wasn’t there.While she was running back to us there was a big explosion.How dangerous!We looked everywhere but did’t find Katy.So we had to set off again for home,feeling father sad.
