Which is true story?

       I hiked a mountain by Lake Biwa with my father 10 years ago. We spent a whole day to climb up and down. When we climb down the mountain, we didn't know where we are. We came to otherside of the mountain. So we decided to hitchhike to a station. Then an old lady took us to a station. That was my first hitchhike.

       I often enjoy fishing at Lake Biwa. One day, I caught a huge fish there. It was about 1m. I could not believe that. It was like a dream. My dad and I put it to our boat with much effort. And we made a new record by that.
