One day, my older brother gave me a DS game that he found on the floor of his high school. I was so excited to have a new game, but I felt bad for the person who dropped it (their save file was on Box, which I thought was a moon at first lol). I tried to continue playing from where they left off, but I had no idea what I was doing and eventually deleted the save file. It has been my favorite game from that point forward :D
