I have made a time machine. It can take people to the past or the future for five hours. I thought that it would be fun to see what my father was like when he was 10 years old.

I got into my time machine and keyed in the words, “1981, 11 Niven Road, New York ” then pressed the button … In a moment, I was in front of a house, 11 Niven Road.

I saw four children looking for a lost dog. They were my father, my uncle Tom, my aunts Peek and Janet. I went up to them and helped them look for their dog, Jack.

We wanted to climb a hill and looked for Jack. When we reached the top, we heard a dog barking. “Jack!” my father shouted . Then we saw Jack was standing in front of a man.

We asked the man to return Jack to us. The man had to give Jack back to us.
