  #Person2#: OK, here's my story, I was about 18 months old I think and I had just started to say my first word. Every time a truck went by, I would shout a word that sounded like a track, but to everyone else, it sounded nothing like it. My parents tried to correct me, but failed. Then, about three months later, we traveled to New York, as we were waiting for our plane at the air?port. I looked out of a huge window, at that very moment I saw the largest truck in the world, I had to tell someone about this. I turned to my father who was standing next to about a thousand people waiting for the very flight and screamed 'Track! Track!' My father tried hard to shut me up, but I was so excited, I kept screaming my special word. My poor mother decided she didn't know this baby and then ran into the ladies-room where she hid until I finally stopped. Well, I learned how to say truck correctly, and soon I was talking like a normal child. However, my parents will never forget the very first word I produced in my life.
