Dear mom and dad,

      We got to the Sunnytown last night. Uncle Sam went to the station to meet us. We had a nice sleep and now

we are sitting next to the window and eating lunch with uncle and aunt.

      Their house is near the amusement park. We can see it through the window. But after lunch we will not

go to amusement. park. We will go to the zoo first and we will ride horses in the zoo! Then we will visit the

museum and we will eat dinner in a restaurant. We will eat my favourite food: fried rice with fruit! 

      It is time to go now. We will write to you again soon!

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Yours Emma & Justin
