When I was 10, my family went to the grand canyon & the adults were talking about how it takes 2 hours to hike down and it can take 4 to 6 hours to go back up. However I misheard them. I thought they said 46 hours, not 4 to 6 hours. I was thinking "Why would anyone want to spend almost two days hiking up a canyon?" A few days later I was thinking about it and I realized my mistake.
